In conclusion, the experiment demonstrated that the combination of NPK and FYM positively influenced the soil health under carrot cultivation.

Impact of Long-Term Application of FYM and Fertilizer Nitrogen on Soil Aggregation and Aggregate Bound Nitrogen Fractions and Nitrogen Mineralization Pattern in Different Size Soil Aggregates: A Review

This review highlights the impact of long-term application of FYM and fertilizer nitrogen on soil aggregation and aggregate bound nitrogen fractions and nitrogen mineralization pattern in different size soil aggregates. Organic manures are an important factor to maintain the soil fertility level because soil organic matter is regarded as a key indicator when assessing soil quality. The integrated application of inorganic and organic amendments leads to increase in both the inorganic fractions (ammonical and nitrate nitrogen) as compare to their alone application. Organic manures and residues that are added to the soil increase the total nitrogen content of the soil by protecting it chemically and physically against microbial degradation. Through FYM and crop root biomass (rhizodeposition), organic matter and fertilizers have been added to the soil on a regular basis during the past 41 years, and the building of nitrogen shows that nitrogen is physically protected within macro aggregates.

Efficacy of Trichoderma asperellum against different pathogens of medicinal plants

Trichoderma asperellum is one of the plant growth-promoting fungi (PGPF) presently marketed as biopesticide, biofertilizer and in soil amendments, due to its ability to protect plants, enhance vegetative growth and reduce pathogen populations. Keeping this in the view, here, we assessed its efficacy against pathogens of medicinal plants in vitro and in field conditions against the Leaf spot disease of Green leaf Tulsi (Ocimum basilicum). We selected 10 different plant pathogens of medicinal plants, namely Ashwagandha (Withania sominifera) pathogens (Alternaria alternata and Fusarium solani); Sarpgandha (Rauwolfia serpentina) pathogens (Colletotrichum sp. and Alternaria alternata); Tulsi (Ocimum basilicum) pathogens (Colletotrichum gloeosporioides and Alternaria alternata); Mint (Mentha arvensis) pathogens (Curvularia sp. and Alternaria alternata); and Mandukparni (Centella asiatica) pathogens (Cochliobolus sp. and Alternaria sp.) for evaluation by Dual culture plate method. After 144 h, maximum inhibition (56.36%) was recorded against F. solani. This was followed by inhibition of Cochliobolus sp. where the reduction was 55.38%. T. asperellum was also found to be effective against Alternaria sp. isolated from Ashwagandha (53.06%), Alternaria sp. from Sarpagandha (53.51%), and Curvularia sp. (52.12%). In field study, FYM enriched with T. asperellum, Pseudomonas fluorescence, neem oil and fungicide were tested against Leaf spot of Tulsi caused by Alternaria alternata. The treatment T5 [soil application of FYM (1.0 kg/m2) enriched with T. asperellum + P. fluorescence talc based formulation each @ 2.0% at planting time+ 3 sprays of copper oxychlorde @ 0.3% with 15 days interval on the onset of disease symptoms] was found effective with per cent disease index recorded 10.37%. This was followed by treatment T6 [soil application of FYM (1.0 kg/m2) enriched with T. asperellum + P. fluorescence talc based formulation each @ 2.0% at planting time + 3 sprays of with bordeaux mixture @ 0.5% onset of disease symptoms], and both the treatments were at par with each other. Maximum biomass of tulsi (3.97 g) observed in treatment T5. The result implies that FYM enriched with T. asperellum and P. fluorescence which was found to be most effective can be incorporated in IDM programs for ecofriendly leaf spot disease management of Green leaf Tulsi.

Effect of Crop Geometry and Nutrient Management Approaches on Yield and Quality of Transplanted Finger Millet

Background: An ideal crop geometry is essential for obtaining optimum plant stand in the field as the yield of a crop depends on the final plant density with effective utilization of growth resources. Conjunctive use of chemical fertilizers and organic manures is important to maintain and sustain soil fertility and crop productivity. Nutrient Management system is gaining importance among the farmers and it is advisable to optimize the use of inorganic fertilizers along with organic manures for getting high yields of better quality besides keeping the production cost at sustainable level. The current field study was aimed to evaluate the impact of various crop geometries and nutrient management treatments on yield and quality of transplanted finger millet. Methods: A Field experiment was conducted at Agricultural college farm, Bapatla during the kharif seasons of 2018 and 2019 and the experimental design was split plot with three replications. The main-plot factor comprised of three crop geometries with different age of seedlings and seven nutrient management practices in subplots. Result: The experimental results indicated that significantly higher grain and straw yields with good quality grain of finger millet were recorded in the spacing of 30 × 10 cm fb 30 × 30 cm spacing and among the nutrient management approaches application of FYM @ 10 tonnes ha-1 + 125% RDF along with wooden log treatment (S6) recorded the highest yield and however was statistically comparable with 125% of RDF + FYM (S5).

Phytosphere management for enhancing root yield and quality in a highly traded medicinal plant Desmodium gangeticum (L.) DC.

Phytosphere management studies for Desmodium gangeticum (L.) DC., an essential herbal remedy used in the Ayurvedic, Siddha, and Unani medical systems, were carried out at AICRP on MAP and B, College of Agriculture, Kerala Agricultural University. Treatments for standardizing shade requirements were 25% shade, 50% shade, 75% shade, and completely open growing conditions. The organic manuring treatments included basal application of FYM @ 10 t/ha, FYM @15 t/ha, vermicompost (to supply N equivalent to FYM 10 t/ha), vermicompost (to supply N equivalent to FYM 15 t/ha), coir pith compost (to supply N equivalent to FYM 10 t/ha), coir pith compost (to supply N equivalent to FYM 15 t/ha) and absolute control. Under 75% shade, the highest root production of 7589 kg/ha was observed. The lowest root yield was produced in the open condition (49% lower than the treatment with the highest yield). According to the findings, D. gangeticum could be used as a component in agroforestry systems with a high shade intensity. The root yields were comparable under 50 and 25% shaded conditions. The basal application of farm yard manure at 10 or 15 t/ha produced the highest root yield and total alkaloid content among organic manures. After two years of the experiment, the soil nutrient status revealed a decrease in the amounts of available nitrogen, phosphorus and potassium compared to the starting level. The absolute control showed the most significant nutrient depletion, emphasizing the importance of providing crops with manures or fertilizers.

COMPARATIVE EFFECT OF INTEGRATED FERTILIZATION APPROACHES ON SOIL HEALTH AND CROP PRODUCTIVITY OF WHEAT (TRITICUM AESTIVUM L.) UNDER DIFFERENT TILLAGE SYSTEMS

The study was conducted at Institute of Soil and Environmental Sciences, University of Agriculture, Faisalabad, Pakistan to monitor the impact assessment of tillage systems on soil health indicators by integrating organic and inorganic resources to sustain wheat production in arid and semi-arid conditions i.e. high temperature and low rainfall. The field experiment was conducted in 2019-20 and carried out in alkaline soil (pH 8.2) with low organic matter (0.45%) to grow wheat after rice and treatments were arranged in randomized complete block design. Farmyard manure (FYM 20.5 Mg/ha), rice crop residues application (CRA 100%) and chemical fertilizers (CF) N-P-K 100-80-60 kg/ha, respectively were used under conventional and conservation tillage systems. During this research different growth and yield parameters were noted and evaluated the level of N, P, K and organic matter contents from soil and plant at the harvest. The results indicated that the combined application of FYM and CRA with CF improved the chlorophyll contents (20% in conventional tillage and 39% in conservation tillage) which helped in nutrient translocation (N, P, K) and increased growth, biological and grain yield by improving soil organic carbon (SOC) and organic matter contents in soil. Growth parameter i.e. germination percentage upto 64%, plant height 27% and spike length upto 35% were increased by T7 . The conservation tillage method was the best where we used T7 i.e. CF + 25% FYM + 50% CRA, and CF + 50% FYM + 25% CRA by conserving moisture and built OM (0.90%), soil organic carbon (0.49%) and mineral nutrition in soil as well as in wheat leaves. It is concluded that the integrated use of organic and inorganic resources are helpful for sustainable wheat production by enhancing fertilizer use efficiency (FUE) to improve soil health especially in arid to semi-arid climate conditions in alkaline soil.

Effect of bio enriched FYM on growth, yield and economics of finger millet (Eleusine coracana (L.) Gaertn) under dryland condition

Crop suffers from the slow release of nutrients from organic manures at initial stages, which may cause a significant reduction in crop yield and farm income. This can be overcome by enrichment of organic manures with beneficial microbial culture and a judicious combination of inorganic fertilizers with such enriched organic manures. Finger millet was grown at AICRP for dryland Agriculture field during Kharif -2019 to study the effect of bio-enriched FYM viz., nitrogen fixers, phosphorus solubilizers, potassium solubilizers, PGPR and microbial consortia with 60 and 80 per cent RDF on growth, yield and economics of finger millet. Application of bio enriched FYM with microbial consortia + 80 per cent RDF (T10) recorded significantly higher plant height (86.38, 111.52 and 115.33 cm), number of tillers per plant (4.42, 5.20 and 5.42) and dry weight per plant (5.50, 15.05 and 27.27 g) at 60, 90 DAS and at harvest, respectively. Whereas, higher grain yield (2999 kg ha-1) and straw yield (4274 kg ha-1) were recorded in T10 treatment Which received 80 per cent RDF with microbial consortia and sème trématent recorded additional return of rupees 12683 per hectare over recommended use of fertilizers. The overall result showed that the bio enrichment of FYM with microbial consortia tended to reduce the application rate of chemical fertilizer and thus microbial consortia along with 80 per cent RDF could be recommended for finger millet.
