Yield Of Pigeonpea Research Articles

Effect of Preparatory Tillage and Mulch on Productivity of Rainfed Pigeonpea [Cajanus cajan(L.) Millsp.

An experiment was carried out at Junagadh (Gujarat) during kharif seasons of 2011 and 2012 to assess the growth and yield of pigeonpea to preparatory tillage (conventional tillage, shallow tillage, row subsoiling and deep tillage) and mulching (control, soil mulch, wheat straw, groundnut shell and weed mulch). The results revealed that deep tillage up to 30 cm soil depth by tractor drawn disc plough and row subsoiling up to 30 cm by tractor drawn two-tyned subsoiler significantly improved growth and yield attributes viz., plant height, plant spread, number of branches/plant, number of pods/plant, number of grains/pod, grain weight/plant and 100-grain weight and thereby increased grain yield (1376 kg/ha) and stalk yield (3207 kg/ha) with higher B: C ratio (2.10) and increased soil moisture content over conventional tillage (cross cultivation followed by blade harrowing and planking). The mulching with wheat straw @ 5 t/ha enhanced growth and yield parameters viz. plant height, plant spread, number of branches/plant, number of pods/plant, number of grains/pod, grain weight/plant and 100grain weight and ultimately increased grain yield (1387 kg/ha) and stalk yield (3212 kg/ha) with higher B: C ratio (1.83) and conserved more soil moisture over no mulch.

Growth and yield of pigeonpea as affected by organic and inorganic fertilization

A field experiment was conducted on PKV-TARA pigeonpea during the Kharif season of 2009-10 at Pulse Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola to study the effect of integrated nutrient management in pigeonpea with an object to optimize the fertilizer dose for getting maximum yield per hectare and the effect of FYM and biofertilizer on growth and yield of pigeonpea. Growth and yield attributes were significantly increased due to the increased level of fertilizer. Incorporation of FYM @ 5 t. ha-1 significantly increased the yield parameters like shelling per cent, 100 seed weight and grain yield. Number of pods plant-1, number of grains pod-1, weight of grains plant-1 and stalk yield were more in seed inoculation of Rhizobium + PSB + PGPR.

Interpretation of genotype x environment interaction and stability analysis for grain yield of pigeon pea (Cajanus cajan L.)

Fourteen pigeon pea (Cajanus cajan L.) genotypes were evaluated for their yield performance at two locations during kharif season of 2009-10 and 2010-11. A significant genotypic difference for yield character was observed. Highly significant genotype–environment interaction indicated differential response of the genotypes to the environmental changes. The stability analysis showed significance of linear component of variation for grain yield. The genotypes TJT-501 (1728.667Kg/Ha) and GRG-2009-3 (1570.000 Kg/Ha) exhibited low meanperformance along with regression value nearer to unity (bi=1) and non significant deviation from regression (S2 di=0) indicating, the high stability and wider adaptability across the different environments. The genotype ICPH-2671 (3134.833 Kg/Ha) exhibited highest mean value and regression value (bi>1) and non significant deviation (S2 di < 0). But genotypes JKM-197 (3072.667 Kg/ha), GRG-2009 (29993.167 Kg/ha), TS-3R (2823.333 Kg / Ha) and ICP-8863 (2740.417 Kg/Ha) exhibited high mean performance but higher regression value (bi>1) and significant deviation (S2 di < 0) value indicating adapted for high performance environments showing these genotypes are sensitive to environments and give maximum yield when inputs are not limited.

Yield, water use and water use efficiency of pigeonpea [Cajanus cajan (L.) Millsp.] under drip fertigation system

Field experiments were carried out during two seasons (August-February) of 2011-12 and 2012-13 at Millet Breeding Station, Tamil Nadu Agricultural University, Coimbatore, to study the effect of drip fertigation on productivity, water use and water use efficiency of pigeonpea (Cajanus cajan) cv. LRG 41. The treatments included three irrigation regimes (50 %, 75 %, 100 % computed water requirement of crop) and surface irrigation along with three fertilizer levels with water soluble fertilizer (WSF) and conventional fertilizers (CF). The treatments were laid out in Randomized Block Design with three replications. The results revealed that drip irrigation at 100 % WRc with fertigation at 125 % RDF through WSF registered significantly highest grain yield of 2812 and 2586 kg ha-1 during 2011-12 and 2012-13, respectively. Surface irrigation with conventional method of fertilizer application recorded lower water use efficiency of 3.70 and 3.38 kg ha-1 mm-1 whereas it was reverse with drip irrigation of 100 % WRc + 125 % RDF through WSF with a WUE of 6.97 kg ha-1 mm-1 during 2011-12 and during second season (2012-13), the highest WUE of 6.72 kg ha-1 mm-1 was recorded in drip irrigation at 50 % WRc along with fertigation at 125 % RDF through WSF. The increase in grain yield with drip irrigation at 100 % WRc + fertigation with 125 % RDF through WSF was mainly attributed by greater and consistent availability of soil moisture and nutrients which resulted in better crop growth, yield components and ultimately reflected on water use efficiency and yield of pigeonpea Cajanus cajan.

Field Performance and Yield of Four Pigeonpea Varieties in Middle Tennessee

As the demand in the United States for legume crops such as pigeonpea [Cajanus cajan (L.) Millsp.] increases, it becomes increasing important to improve yield and extend the area where pigeonpea may suitably be grown. To understand the effect of agricultural management on the leaf physiology, growth, and yield of pigeonpea, a 3‐yr (2010–2012) field experiment was conducted in Nashville, TN. A split‐split‐plot experimental design with two planting dates in years 2010 and 2012, and one late planting in 2011 were used (main plot factor, early and late planting). Four pigeonpea varieties (subplot factor, GA1, GA2, W1, and W3) at three plant densities (sub‐subplot factor, 295,500, 145,250, and 96,833 plants/ha) were planted. Maximum leaf photosynthesis, stomatal conductance, transpiration, plant height, plant stem diameter, leaf area index (LAI), and seed yield were measured. There were significant differences in leaf physiology, growth and yield among varieties, between planting dates, and between years. Leaf transpiration (5.4 mmol H2O/m2/s) and yield (1048 kg/ha) were higher at early planting than at late planting (4.8 mmol H2O/m2/s, 2.64, and 629 kg/ha), but height (138 cm) was lower at early planting than at late planting (150 cm). Among varieties, GA2 plants were shorter (131 cm) and had lower LAI (1.61), but produced higher seed yield (1263 kg/ha). Plant density did not show significant influence on leaf physiology, LAI, or yield. All variables measured showed remarkable variation between years. Our results indicated that variety selection and early planting may improve pigeonpea growth and yield in middle Tennessee.

Two rhizobacterial strains, individually and in interactions with Rhizobium sp., enhance fusarial wilt control, growth, and yield in pigeon pea.

A Pseudomonas aeruginosa strain, RRLJ 04, and a Bacillus cereus strain, BS 03, were tested both individually and in combination with a Rhizobium strain, RH 2, for their ability to enhance plant growth and nodulation in pigeon pea (Cajanus cajan L.) under gnotobiotic, greenhouse and field conditions. Both of the rhizobacterial strains exhibited a positive effect on growth in terms of shoot height, root length, fresh and dry weight, nodulation and yield over the non-treated control. Co-inoculation of seeds with these strains and Rhizobium RH 2 also reduced the number of wilted plants, when grown in soil infested with Fusarium udum. Gnotobiotic studies confirmed that the suppression of wilt disease was due to the presence of the respective PGPR strains. Seed bacterization with drug-marked mutants of RRLJ 04 and BS 03 confirmed their ability to colonize and multiply along the roots. The results suggest that co-inoculation of these strains with Rhizobium strain RH 2 can be further exploited for enhanced growth, nodulation and yield in addition to control of fusarial wilt in pigeon pea.

Residual Effect of Phosphorus Fertilizer on Yield of Pigeon Pea (Cajanas cajan) in Ultisol

Phosphorus (P) is one of the essential plant nutrients and plays an important role in nitrogen fixation of leguminous crops. A two-year experiment was conducted at the Teaching and Research Farm of Ambrose Alli University, Ekpoma, Nigeria to investigate the effect of different rates of phosphorus fertilizer on the growth, yield, nodulation and nutrient uptake of pigeon pea ( Cajanas cajan ). Seven P rates (0kg (control), 25, 50, 75, 100, 125 and 150kg ha -1 ) were laid out in a Randomized Complete Block Design with three replicates and managed for two consecutive years. Data on plant growth, yield, nutrient uptake and soil properties were collected for the two seasons. The application of phosphorus significantly increased the soil nutrient content after the first season. There was no significant difference in height and stem girth of pigeon pea. The application of 75 kg ha -1 significantly (p=.05) increased the number of leaves, biomass and nodules of pigeon pea. The application of 25 - 75kg ha -1 of phosphorus fertilizer increased the grain yield of pigeon pea than other rates of application in the first cropping season. In the residual experiment, the control and 25kg ha -1 application of P had the grain yield of 1,493.3kg ha -1 and 1,498.0kg ha -1 respectively, and were significantly (p=.05) higher compared to other treatments. The application of phosphorus fertilizer at the rate of 25 ‐ 75kg ha -1 significantly improved the yield, nodulation and nutrient uptake of pigeon pea in

Effect of Climate on Productivity of Pigeonpea and Cotton in Andhra Pradesh – A Panel Data Regression

This paper was attempted to examine the effect of temperature and rainfall on the productivity of two important crops-pigeonpea and cotton in Andhra Pradesh following panel data regression approach. Using the district level time series data, the yield of each of these two crops was regressed on maximum temperature during kharif, rainfall quantity and number of rainy days for the period 1990–2002, in a one-way and two-way fixed effect models of panel regression using Least Squares Dummy Variable Method. Comparison of district specific effects revealed statistically significant differences between districts in case of pigeonpea. The response coefficients for rainfall and number of rainy days were found significant at 5 per cent level. A positive impact on yield of pigeonpea at the rate of 1.9 kg/ha was observed for a 10 mm rise in rainfall. The number of rainy days was found to have a significant negative relationship with yield. In case of cotton, half of the major cotton growing districts differed significantly in mean yield levels. A significant reduction in yield at a rate of 13 kg/ha for every 1°C rise in the maximum temperature was observed. The yield of cotton was found to increase by 0.7 kg/ha for every 10 mm increase in the rainfall.

Association Analysis for Yield and its Component Traits in F<sub>3</sub> and F<sub>4</sub> Populations of Pigeonpea (<i>Cajanus cajan</i> (L.) mill Sp.)

An investigation was carried out in pigeon pea to understand the association among the yield components and their direct and indirect effects on the seed yield. Character association studies indicated that days to maturity, number of seeds per plant, number of pods per plant, test weight (gm), seed yield per plant (gm) shows significant positive correlation with seed yield per plant at genotypic and phenotypic level in F 3 and F 4 generation. Path coefficient analysis revealed that number of seeds per pod, number of pod per plant and test weight (gm) were the most important character which can be strategically used to improve yield in Pigeon pea.

Insect Pollinators in CGMS Hybrid Seed Production of Cajanus cajan

Pigeonpea [Cajanus cajan (L.) Millspaugh] is the only shrubby food legume crop with drought tolerance in the world. Insect pollinators are essential to flower pollination in cytoplasmic genetic male sterility (CGMS) pigeonpea lines, and the species, abundance, and visiting frequency of insect pollinators are the key factors for pigeonpea hybrid production. More than 46 species of insects have been reported to be flower visitors in the open field for pigeonpea production outside China, of which Megachile spp. are the major pollinators. In this study, the species, abundance, and visiting frequency of flower-visiting insects at flowering stage, as well as hybrid yield of pigeonpea, were investigated in the pigeonpea hybrid production field in Yuanmou County, Yunnan Province, China, using CGMS-based ICPH2671 hybrid. A total of 25 species of flower-visiting insects were detected, including 5 major pollinator species, Megachile velutina Sm., Megachile sp-5, Xylocopa tenuiscapa Westw., Apinae sp-1, and Megachile sp-2. At the blooming stage, the flower-visiting insects visited each primary branch at a frequency of 2.8 times per 10 min for the CGMS male sterile line, while at a frequency of 5.2 times per 10 min for the CGMS restorer line. This indicated the preference of flower-visiting insects to the flowers of restorer line. This significant difference between the male sterile and the restorer lines resulted in very similar dry seed yields of the male sterile line (383.7 g per plant) and the restorer line (357.0 g per plant). Therefore, enough pollens can been transported from the restorer line to the male sterile line by insect pollinators, even much less visiting frequency on the flowers of male sterile line compared to that of the restorer line.

Effect of transpiration suppressants and nutrients on productivity and moisture-use efficiency of pearlmillet (Pennisetum glaucum) – pigeonpea (Cajanus cajan) intercropping system under rainfed conditions

A field experiment was conducted at IARI, New Delhi during 2009 and 2010 to study the effect of cropping systems, transpiration suppressants and nutrient management on productivity and moisture-use-efficiency of pearlmillet (Pennisetum glaucum L.) – pigeonpea [Cajanus cajan (L.) Millsp.] intercropping system under rainfed conditions on a sandy loam soil. There was significant superiority in yield attributes as well as yield of pearlmillet and pigeonpea under sole cropping as compared to their intercropping system. Pearlmillet equivalent yield and land equivalent ratio was significantly higher with intercropping system (2:1 ratio). Intercropping system recorded the higher moisture-use-efficiency and economics as compared to either of the sole cropping. Rate of moisture use was more in sole pearlmillet (3.92 mm/day) than sole pigeonpea and intercropping system. The results showed significant improvement in all yield attributes and yield as well as moisture use and economics due to spray of transpiration suppressants over the control under inadequate moisture conditions. The total number of nodule and nitrogenase activity significantly differed in pigeonpea crop under different fertilizer doses as compared to control. Among fertility levels, application of 50 kg N + 17.2 kg P/ha, followed by 25 kg N 8.6 kg P/ha + BF resulted in better performance of crops over other treatments.

Response of Intercropping and Integrated Nutrition on Production Potential and Profitability on Rainfed Pigeonpea

A field experiment was conducted during kharif season 2008-09 and 2009 - 10 to evaluate the response of pigeonpea [Cajanus cajan (L.) Millsp.] + blackgram (Vigna mungo L.) intercropping system to integrated nutrient levels. Intercropping failed to influence the dry matter production /plant, CEC of roots, root N content, yield and quality parameters of both crops. Both the intercropping system gives significantly higher uptake of N, P and K when compared to sole pigeonpea. The available soil N, P, K after harvest of crop (s) was maximum observed under sole pigeonpea followed by normal intercropping and lowest inpaired intercropping. Application of 100% RDF+50% RDN+5 kg Zn/ha significantly increased the dry matter production /plant,CEC of roots, root N content, grain yield, protein content, protein harvest (kg/ha) and nutrient uptake (NPKS and Zn) in pigeonpea and black gram cropping system. Integrated use 100% RDF with 50% RDN and 5 kg Zn/ha also significantly improved the available N, P and K soil after harvest during both the years.The maximum net return (Rs. 117010) was obtained with combination of normal intercropping system + 100% RDF+50% RDN+5 kg Zn/ha followed by normal intercropping system + 50% RDF+100% RDN+5 kg Zn/ha (Rs. 115102).

Inheritance of resistance to Fusarium wilt and yield traits in pigeonpea

Fusarium wilt is the main pigeonpea production constraint in Malawi. The purpose of the study was to understand the nature and mechanism of inheritance of F. wilt resistance, yield and secondary traits in pigeonpea. 48 crosses were generated in a 12 lines × 4 testers mating scheme. Some F1 plants were selfed for segregation analysis for inheritance pattern of resistance, while others were evaluated for resistance, yield and secondary traits. There were significant variations among F1 plants for F. wilt, days to 50 % flowering, seed/pod, and number of secondary branches. Specific combining ability (SCA) effects were predominant for F. wilt, days to 50 % flowering and number of secondary branches. The general combining ability (GCA) effects, mainly due to maternal genotypes, were preponderant for yield and other secondary traits. The significance of GCA and SCA effects suggested that variations were due to additive gene action in both the testers and parental lines arising from their interactions, and the dominance effects due to interactions of the parental lines. The χ2 analysis suggested dominant patterns of inheritance for wilt in most of the F2 populations. The segregation ratios of 3:1, 15:1, and 9:7 suggested the involvement of single or two independent/complementary dominant genes in the test donors. Involvement of a few genes governing wilt resistance suggested the ease of breeding for this trait. Pedigree breeding method would be recommended for incorporating various traits in pigeonpea.

EVALUATION OF FRESH AND STORED HANPV FORMULATIONS ON HELICOVERPA ARMIGERA (HUBNER) LARVAL POPULATION AND PRODUCTION OF CAJANAS CAJAN (L. MILL)

ABSTRACT Pigeonpea is an important pulse crop damaged mainly by pod borers causing serious losses in pigeonpea yield. Investigations were carried out through field evaluation conducted at the research farm to evaluate the efficacy of stored HaNPV formulations [1- fresh HaNPV (2x109 POBs/ml@250 ml/ha and 1x109 POBs/ml@500 ml/ha.); 2 - stored HaNPV for 1 year (2x109 POBs/ml@250 ml/ha and 1x109 POBs/ml@500 ml/ha)] were found effective in larval reduction and keeping population of Helicoverpa armigera Hubner at its minimum levels and obtaining higher yields of pigeon pea. Despite longer storage of HaNPV for 2 years it is comparatively more effective in reducing H. armigera larvae than the 3 year old formulations.

Changing weather and introduction of pigeon pea intercrop in formerly cold pyrethrum zone

Pyrethrum is a, herbaceous perennial crop grown commercially for extraction of pyrethrins, which is used in pesticides formulation. Through out the years, it has been grown in a pure stand due to its poor performance as intercrop with other crops that do well in pyrethrum growing areas. A trial was carried out on introduction of a short pigeon pea variety at different line spacing within the pyrethrum crop in randomized complete block design replicated four times. Data on dry pea yields was analyzed using ANOVA and fitted in a generalized linear model, with the distribution assumed to be Gamma and a link function as inverse. The results showed that there was a significant difference (F(4, 132) = 4.76; p=0.001) among the intercropping levels of pyrethrum and pigeon pea. The control (pure stand of pigeon pea had the lowest yield (0.92 t ha-1) as compared to 1:1 intercropping of pyrethrum and pigeon pea which had the highest pigeon pea yield (1.12 t ha-1). Comparison of pigeon mean yield showed that there were significant differences (p 0.05) in pigeon pea yields were found among all intercropping spacing. These findings indicated that pigeon pea might be a good option to inter crop with pyrethrum. Further monitoring and assessment would be carried out to assess both pyrethrum and pigeon pea yield at different seasons of the year. It was observed that means of the rows were significantly different with pigeon pea pure stand giving the lowest. This observation indicated that pigeon pea is a good option to inter crop with. In all spacings the pigeon pea performed well. If interest would be the quantity of pigeon pea then 1:1 spacing would be resulted to Key words: Field productivity, soil microbial symbiotic association, soil nutrient availability.

Studies on yield limiting meteorological factors for production of rabi pigeon pea in West Bengal

Winter pigeon pea can be considered as an alternative to boro rice cultivation particularly in the places where over exploitation of ground water is a potential threat to sustainability. The present experiment was aimed at quantifying the meteorological factors that limit the cultivation of rabi pigeon pea particularly in the upland and medium land condition. The experiment was conducted for three consecutive years during 2003-06 in the University Farm at (BCKV) Kalyani W.B. The treatments comprised different dates of sowing at seven days interval between 20 September and 7 December. The influence of meteorological factors on phenological development and yield was statistically analysed. The results revealed that the length of vegetative phase was inversely correlated to the afternoon vapour pressure deficit, average BSH and diurnal variation in temperature. On the other hand, night temperature and daylength were negatively correlated with the reproductive duration. The regression analysis showed that bright sunny days with high atmospheric vapour demanded not only induced early flowering but they also had suppressed the grain yield. Higher accumulation of GDD and PTU during vegetative phase resulted in higher grain production. On the other hand, the average day temperature, night temperature and day length during reproductive phase had negative correlation with grain yield of pigeon pea. These parameters may be considered as limiting factors for higher production. Besides that, rainfall during March had severely hampered pod formation when sown late.

Competition between maize and pigeonpea in semi-arid Tanzania: Effect on yields and nutrition of crops

Productivity of maize–pigeonpea cropping systems is dependent on facilitative and competitive interactive effects on resource availability. Controlling these interactions may benefit farmers through increased productivity associated with optimized crop yields. Previous research on maize–pigeonpea culture in Sub-Saharan Africa has focused on yield and soil fertility, but provided inadequate information on the mechanisms of possible interspecific competition. We employed a factorial field experiment to examine yield and nutritional responses of maize and pigeonpea to cropping systems (sole maize, intercropping, and improved fallow), N and P fertilizer additions, and cattle manure additions in Dodoma, Tanzania. The study objectives were to assess competition between crops and to determine how manure or fertilizer inputs may mitigate such interactions to improve yields. Intercropping enhanced maize yield over sole maize only when fertilized, reflecting probable nutrient competition. Improved fallows alone or with fertilizers (1.2–1.6 Mg ha −1) increased maize yields over sole maize (0.6 Mg ha −1). These increases were attributed to pigeonpea facilitation through soil nutrient replenishment, reduced competition associated with sequential cropping arrangements, and added nutrients from fertilization. Combined fertilizer and manure applications also improved maize and pigeonpea yields. Plant nutrient diagnosis indicated primary and secondary P and Ca deficiencies, respectively associated with P-fixation and leaching of cations due to high soil acidity and exchangeable Al. Maize competed strongly in mixture suppressing biomass and grain yields of the unfertilized pigeonpea by 60% and 33%, respectively due to limited soil nutrients and/or moisture. These yield reductions suggest that the intercropped pigeonpea did not recover from competition after maize harvesting that reduced competition. Optimizing yields of both maize and pigeonpea would require the addition of prescribed fertilizer when intercropped, but applications can be reduced by half under the improved fallow system due to alleviating interspecific competition.

Sustainable Management of Dryland Alfisols (Red Soils) in South India

A community based cooperative research project was implemented on farmers' fields on some dryland Alfisols in Tamil Nadu, India, to demonstrate and validate improved dry-farming technologies, such as: 1) soil and water conservation and water harvesting; 2) cropping systems, including intercropping and double cropping; 3) recycling of processed agricultural wastes and byproducts; and 4) low-cost drip irrigation. Disc plowing to 30 cm depth during summer and contour bunding enhanced soil moisture storage in the profile, and facilitated harvesting of runoff water into a community pond. Under the bimodal rainfall pattern in the region, among the medium- and long-duration varieties of pigeon pea, short-duration varieties of blackgram and greengram evaluated, long-duration variety of pigeon pea was the most suited to this region. The pigeon pea variety ‘VBN2’, blackgram variety ‘VBN3’, and greengram variety ‘VBN2’ produced the maximum grain yields. Increasing the land equivalent ratio (LER) by intercropping of pigeon pea with pulses and oilseeds enhanced agronomic productivity. Pigeon pea + groundnut was the best intercropping system. Pigeon pea + lablab and pigeon pea + groundnut intercropping system produced the highest yields. In years with normal rainfall, green manuring with sunnhemp and raising a pulse crop, horsegram, increased soil fertility. Application of compost enriched with rock phosphate (produced by using locally available crop residues of cotton, pigeon pea, sugarcane, and raw pressmud) significantly enhanced the yield of pigeon pea, groundnut, onion, and okra in these degraded Alfisols with high phosphate fixation capacity. Tied ridging and mulching with groundnut residues produced the maximum yield of cowpea even in seasons with below normal rainfall. Tied ridging produced the highest net returns from pigeon pea + greengram intercropping system. A low-cost, zero-energy drip-irrigation system produced the highest yield of 23.2 Mg/ha of tomato, with a saving in water of 73.8% compared with the control. Introduction of arid horticulture with amla, sapota, and mango, and water management through pitcher-pot irrigation and mulching with coconut husk as a means of diversification of land use management, provided employment during the off-season and enhanced household income.

Biological control ofFusarium wilt of pigeonpea byPantoea dispersa, a field assessment

Fusarium wilt is one of the major yield and growth-limiting factors of pigeonpea (Cajanus cajan). For an ecofriendly and sustainable management of such a disease, a novel mycolytic strainPantoea dispersa was evaluated against fungal pathogenFusarium udum that is known to be infecting the susceptible variety of pigeonpea (T-15-15), commonly prevalent in India. To study the efficacy ofP. dispersa as a biocontrol agent in comparison with chemical fungicide Bavistin and antifungal biocontrol agentTrichoderma Monitor WP was studied in both pot and field experiments.In vitro, P. dispersa inhibits the growth ofF. udum. In the pot experiment,P. dispersa the treated pigeon pea (T-15-15) seeds showed higher percentage of seed germination and decreased wilt incidence as compared to chemical fungicide; Bavistin and antifungal biocontrol agentTrichoderma Monitor WP treatments. Moreover, the root, shoot lengths and growth were also found to be higher. Due to high impact ofP. dispersa inin vitro condition on controlling theF. udum growth, further study was conducted in field in a wilt-stricken plot. These studies were repeated for three cropping seasons (2004/2007). The seed dressing byP. dispersa reduced wilt incidence (47%) during field trials, which is greater than Bavistin (41%) andTrichoderma Monitor WP (36%) treatments. HenceP. dispersa was proven superior toTrichoderma Monitor WP and Bavistin; which are used as commercialFusarium wilt control agents.
