Effect of Drip Fertigation on Growth, Yield and Quality of Ratoon Sugarcane

A field experiment was conducted at Zonal Agricultural Research Station, V.C. Farm, Mandya, Karnataka, India during Kharif 2020-21. The effect of water-soluble fertilizers on performance of ratoon sugarcane (Saccharum officinarum) as influenced by fertigation through surface drip irrigation was studied. The soil at the experimental site was red sandy loam with neutral pH (6.7), normal electrical conductivity (0.21dS m-1), medium organic carbon (5.2 g kg-1), low available nitrogen (275 kg ha-1), medium phosphorus (35 kg ha-1) and potassium content (280 kg ha-1). The experiment was laid out in Randomized Complete Block Design with three replications comprising seven treatments using VCF-0517 sugarcane mild late (12-14 months) maturing variety. The application of WSF at 125 per cent RDF (312.5:125:156:N:P2O5:K2O) through drip fertigation showed significantly superior growth and yield attributes viz., plant height (357.0 cm), no. of tillers clump-1 (15.0), internode length (16.67 cm), cane dry weight (54.8 t ha-1), millable canes (8.17 clump-1), cane length (341.67 cm), cane girth (3.30 cm), single cane weight (2.40 kg), number of internodes cane-1 (21.40) and cane yield (182.67 t ha-1). Also, superior juice qualities such as juice extraction percentage (70) and sugar yield (20.88 t ha-1) were recorded. The results clearly indicated application of water-soluble fertilizers at 125 per cent RDF through surface drip fertigation resulted in higher growth and yield of sugarcane due to enhanced water and nutrient use efficiency.

Monitoring the effects of pH and EC regulated drip fertigation on microbial dynamics of calcareous soil in tomato (Solanum lycopersicum L.) cultivation under greenhouse conditions in a Mediterranean climate

The microbial dynamics of the soil, together with the available nutrient content of the soil, is seen as a very important indicator of soil fertility. In this study, the effects of drip fertigation with different pH and EC applications in the cultivation of tomato under greenhouse conditions on microbial dynamics of calcareous soil were investigated using number of bacteria (heterotrophic aerobic mesophilic) and enzyme activities (urease, alkaline phosphatase, β-glucosidase, dehydrogenase). pH and EC regulated fertigation applications on soil are as follows: a) pH 7.2 EC 2.0 dS m−1 (NA+CF-1), b) pH 7.2 EC 3.5 dS m−1 (NA+CF-2), c) pH 6.5 EC 2.0 dS m−1 (NA+CF-3), d) pH 6.5 EC 3.5 dS m−1 (NA+CF-4), e) pH 5.0 EC 2.0 dS m−1 (NA+CF-5); and f) pH 5.0 EC 3.5 dS m−1 (NA+CF-6). Results indicated significant effects of both pH and EC regulated fertigation on soil in terms of enzyme activities (except urease and dehydrogenase) and the presence of bacteria. The measured parameters showed greater values in the first growth season compared to the second (except urease) and the differences between the treatments in the first growth season were statistically significant. In addition, in both growth season, positive relations occurred between number of soil bacteria and total N, available P, urease and alkaline phosphatase activities. On the other hand, due to increasing salinity (in the second growth season) number of soil bacteria, alkaline phosphatase, β-glucosidase and dehydrogenase activities are negatively affected. It would be ideal to have the pH of the water to be dripped to rhizosphere in the range of 6.5-7.2 and the EC in the level of 2.0 dS m−1 in order to provide more efficient and safer protection of the soil fertility in terms of soil microbial dynamics during the tomato cultivaton in calcareous soils under the Mediterranean climate.

Effect of Drip Fertigation under Different Fertilizer Levels on Nutrient Status in Coconut (Cocos nucifera L) Leaf

A study was conducted during 2017-18 under the All India Co-ordinated Research Project initiated in 2009 at research farm of Bihar Agricultural University, Sabour, Bhagalpur. The aim of this study was compare the nutrient concentration of coconut leaves at different nutrient levels through drip fertigation in a Randomized Block Design (RBD) with four (4) replications. Result was observed that leaf Nitrogen, Phosphorous, Sulphur, Iron, Manganese, Copper and Boron content under different fertigation treatments were not significantly different from each other. The content of micronutrients in leaf were found to increase with increasing levels of fertilizer in the treatments. Cation Exchange Capacity was positively correlated with all the leaf nutrients. Organic carbon did not show remarkable relation with plant nutrient parameters. Soil K content of all three depths was positively correlated with all the leaf nutrient elements. Soil pH value was positively correlated with leaf P content in coconut which explains that leaf P content is directly proportional to the soil pH value. Electrical conductivity (EC) of soil was also positively correlated with P, K and B concentration in coconut leaf. Correlation coefficient value between CEC and leaf nutrient contents explains that 2nd depth of soil is more important for mineral nutrition of coconut palm. Correlation coefficient values between soil P content and leaf nutrient content. Higher correlation coefficient value was found at lower soil depth between available sulphur content in soil and sulphur content in leaf of coconut. This result suggests that inherent supplying capacity of micronutrient of experimental soil is not so influential for higher plant growth, but application of N, P and K fertilizers trigger the absorption capacity for micronutrient from soil. Under different NPK levels, the applied NPK does not have significant effect on leaf N, P, S, Zn content after five (5) years of experimentation while the effect was found to be significant for few elements like K, Fe, Mn, Cu, and B. An increasing trend was observed for leaf nutrient content with increasing levels of fertilizer application.

Effect of Drip Fertigation with Nitrogen Application on Bioactive Compounds and the Nutritional Value of Potato Tubers before and after Their Long-Term Storage

The nutritional value and the content of bioactive compounds in potato tubers are influenced by many soil, climate and agrotechnical factors. This study investigated the effect of drip irrigation and nitrogen fertilization by broadcasting and fertigation on the content of dry matter, starch, monosaccharides, total sugars, vitamin C, polyphenolic compounds, chlorogenic acid and antioxidant activity in tubers of “Augusta” potatoes. Additionally, the magnitude of the changes in the tested components during their long-term storage (6 months) was also assessed. Drip irrigation had a significant positive effect on the content of dry matter, starch, vitamin C, monosaccharides, sucrose, total sugars, total polyphenols, chlorogenic acid and antioxidant capacity. Compared to broadcasting fertilization, fertigation significantly increased the content of vitamin C, total polyphenols and chlorogenic acid, as well as the antioxidant activity of potato tubers. Long-term storage contributed to a decrease in the tested components. The exception was the content of monosaccharides, where a more than twofold increase was noted, especially in the case of irrigated tubers. The results of the research showed a beneficial effect of drip irrigation and fertigation on the content of bioactive compounds and the nutritional value of “Augusta” potato tubers.

Effect of Drip Fertigation and Mulching on Yield Parameter and Water Productivity of Pigeonpea (Cajanus cajan L.)

Background: Pigeonpea is second most important pulse crop grown after chickpea in India. Pigeonpea is versatile crop can be grown in vast agro climatic condition with low input. Although the yield is very less as compare to the potential yield, so we need to increase the yield of pigeonpea using modern techniques such as drip fertigation and mulching. Both these techniques are resource saving and realized maximum yield as compare to conventional practices. Methods: The experiment was laid out in factorial complete randomized block design with three replications. The experiment consisted of two levels of irrigation (0.50 CPE and 0.75 CPE) as one factor and three fertility levels (100% RDF,75% RDF and 50% RDF) as second factor and two levels of mulching (without mulching and with plastic mulching 25 micron) as third factor. Result: The results revealed that the combination of higher level of irrigation with 100 per cent RDF and with plastic mulching recorded significantly higher seed yield, water productivity and B.C ratio compared to the rest of the treatment combination.

Nutrient uptake, soil nutrient status and water use efficiency as influenced by drip fertigation in broccoli (Brassica oleracea var. italica)

Nutrient uptake by plant and nutrient status of soil after harvesting of crop varies markedly under fertigation and soil fertilization. A two year experiment was conducted at Vegetable Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India during the rabi seasons of 2016–2017 and 2017–2018 to study the effect of drip fertigation with levels and scheduling on nutrient uptake, soil nutrient status and water use efficiency in broccoli. The experiment was laid out in two factorial randomized block design with one additional treatment consisting of five fertigation levels and three fertigation scheduling along with control (soil application of RDF with flooding) replicated thrice. Increasing the fertigation levels favors in increasing the nitrogen, phosphorus and potassium uptake irrespective of the crop growth stage. At harvest, N, P and K uptake by broccoli under fertigation increased by 10.47, 17.39, 12.21% and 18.08, 15.88, 9.96% compared to the soil fertilization in the first and second year, respectively. Fertigation treatment increased the available phosphorus by 11.73 kg compared to soil fertilization. Available potassium content in soil after harvesting of crop depleted when compared to initial value. The consumptive water used for both the years varies between 150 mm and 195 mm under different fertigation treatments as compared to 300–325 mm under traditional method of irrigation. Fertigation treatments registered significantly higher WUE of 78.31 kg ha−1 mm−1 and it was higher by 95.48% over the conventional method of irrigation (40.06 kg ha−1 mm−1).

Effect of Drip Fertigation with Nitrogen on Yield and Nutritive Value of Melon Cultivated on a Very Light Soil

Most species of Cucurbitaceae respond favorably to irrigation, especially when combined with fertilizers. The effect of drip irrigation combined with nitrogen fertigation in melon grown on a very light soil in Central Poland, during 2013–2015, was evaluated. The field experimental design was a split-plot with four replications. Two factors were studied: (1) irrigation treatments applied in two combinations—drip irrigation + broadcast nitrogen fertilization (control), and drip irrigation + fertigation with nitrogen; (2) two cultivars—Melba and Seledyn. The total marketable yield of fruits, weight of a single fruit, and the concentration of dry matter, total sugars, monosaccharides, ascorbic acid, total carotenoids, and polyphenols were evaluated. Tested factors presented a significant effect both on the yield and nutritive value characteristics. Drip irrigation combined with nitrogen fertigation, comparing to the control, notably improved yields and nutritional value of fruits. Seledyn produced better yields than Melba. This study shows that on very light soil, with low water and nutrient retention capacity, melon should be drip-irrigated and nitrogen-fertigated to obtain the best cultivation results.

Effect of drip fertigation on yield and quality of guava under ultra high density planting in Tamil Nadu

The new concept of UHDP in mango and guava is still a new technology to the growers of Tamil Nadu to increase the fivefold increase in production and they need an elaborate demonstration to adopt and to practice the technologies for fertigation. The present investigation was aimed at studying the effect of fertigation of guava under ultra-high density planting on growth and yield. An experiment was conducted at Horticultural College and Research Institute, Periyakulam in the year 2018-2019 with a spacing of 3 x1.5m. The trial was laid out in a Randomized Block Design (RBD) with five set of treatments with water soluble fertilizers (WSF) and conventional fertilizers. The pooled yield revealed that the application of 100% RDF through water soluble fertilizers(T2) recorded highest fruit yield of 39.73 t ha-1, followed by T1 - 75% RDF through water soluble fertilizers recorded highest fruit yield of 38.15 t ha-1while the control (T5) recorded the lowest of 24.8 t ha-1, The same treatment recorded the highest in quality parameters with reducing sugar (6.72%), non-reducing sugar(5.05%) and lowest acidity(0.41%) while in However, the cost economics shows that 75% RDF through water soluble fertilizers recorded highest BC ratio of 3.65 over the control of 2.42. Hence 75% RDF as water soluble fertilizers can be advocated in increasing the yield and quality of Guava under UHDP.

Nutrient Use and Yield of Banana as influenced by Fertigation

A field experiment was conducted during 2010-2011 in medium deep clay soils at the Research Farm of Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra to find out the effect of drip fertigation on yield and nutrient use efficiency of banana (cv. Grand naine). The treatments comprised of 100, 80 and 60 % recommended dose (RD) of fertilizer applied through drip in two schedules (Schedule A-equal, Schedule B crop growth stage), drip irrigation with only N through drip, drip with conventional fertilizers through soil and surface irrigation as control. The drip irrigation increased banana yield by 59.6 per cent and saved fertilizer to the tune of 40 per cent .The treatment comprising of 100 % RD of fertigation (schedule B) had maximum banana yield (81.84 t ha-1) over surface irrigation (51.26 t ha-1), however, it was at par with 100 % RD of fertigation in uniform 16 splits and 80 % RD of fertigation. Application of water soluble fertilizers through drip resulted in highest nutrient availability than control. In general, 100 % RD had the highest nutrient availability than 80 % and 40 % RD of fertilizer. The nutrient availability was more in treatment in which fertilizers were applied as per growth stages (schedule B) than equal splits (schedule A). The uptake of nutrients was higher in fertigated treatments than other treatments

Effect of drip fertigation on productivity and profitability of castor (Ricinus communis L.)

A field experiment was conducted at the Main Oilseeds Research Station, Junagadh Agricultural University, Junagadh (Gujarat) during kharif for three consecutive seasons of the year 2013-14, 2014-15 and 2015-16. The experiment was laid out in randomized block design, with four replications. The soil was medium black in texture. The seven treatments comprised oftwo levels of drip irrigation [at 0.6 and 0.8 Pan Evaporation Fraction (PEF)] with combination of three levels of nitrogen (50 %, 75 % and 100 % of recommended dose through fertigation) and check basin method of irrigation 0.6 IW/CPE ratio with IWof 50 mm. Drip system(4 LPH) was operated after every third day for 2 hours during October and for 1 hour and 45 minutes during November to January. The pooled analysis of results revealed that drip fertigation at 0.8 PEF in conjunction with nitrogen fertigation @ 90 kg/ha in the form of urea (20 kg as basal and 70kg in five equal split doses at 12 days interval) resulted in the highest seed yield (3541 kg/ha), net returns (Rs. 90712/ha) and B:C ratio (3.25). Drip fertigation also recorded saving of 25% nitrogen fertilizer and better water use efficiency. The highest water use efficiency of 12.26 kg/ha mmwas obtained under drip fertigation at 0.6 PEF +100% RDN (T3).

Effect of Drip Fertigation on Potato Productivity with Basal Application of Loss Control Fertilizer in Sandy Soil

AbstractTo establish appropriate drip fertigation scheduling with loss control fertilizer (LCF) as a basal fertilizer in sandy soil, a 2‐year field study was conducted to evaluate the effects of five fertilizer levels (10, 30, 50, 70 and 90% of the recommended fertilizer dose (RFD) in 2012, and 10, 35, 60, 85 and 110% of RFD in 2013) on potato biomass, tuber yield and fertilizer and irrigation water productivity. All LCFs were applied as basal fertilizer while drip fertigation was applied when soil matric potential at 0.2 m depth under the emitters reached –25 kPa. Results showed 35–60% of RFD resulted in a better dry matter distribution between above ground and tubers during tuber bulking. Tuber yield initially increased and then decreased with increasing fertilizer rates in both seasons. The highest irrigation water productivity was for 50% of RFD in 2012 and 35% of RFD in 2013. Fertilizer productivity decreased slowly after fertigation level increased to about 50% of RFD. Therefore, 35–50% of RFD is suggested scheduling for potato production in sandy soils under drip fertigation with LCF as basal fertilizer in arid and semi‐arid regions in the north of China.

Effect of drip fertigation and polythene mulching on growth and productivity of coconut (Cocos nucifera L.), water, nutrient use efficiency and economic benefits

A field experiment was conducted to study the effect of drip irrigation, fertigation and polythene mulching on coconut (Cocos nucifera L.) var. VHC 3. The experiment was laid out in Randomized Block Design (RBD) with seven treatments and three replications. The treatments comprised of 100% (T1), 80% (T2) and 60% (T3) recommended dose of fertilizer with 100μm thickness polythene mulch and 100% (T4), 80% (T5) and 60% (T6) recommended dose of fertilizer without polythene mulch. The control was with conventional method of irrigation (basin irrigation) without mulch (T7). The recorded data on the growth and yield of coconut revealed that the plant height, canopy development and other plant growth parameters were higher in the treatment with 100% recommended dose of fertilizer (0.50:0.32:1.20kg of NPK tree−1) with 100μm thickness polythene mulch (T1) when compared to other treatments. The maximum yield attributes viz., spathe length, number of inflorescence, number of bunches/palm/year and number of nuts/bunch of 127.76cm, 13, 13 and 31, respectively were recorded in 100% of recommended dose of drip fertigation with 100μm polythene mulching. The lowest spathe length, number of inflorescence, number of bunches/palm/year and number of nuts/bunch of 92.16cm, 8, 8 and 12, respectively were recorded in control treatment without mulch. The number of nuts per palm, an important yield contributing trait was promising with 292 nuts/palm/year in 100% of recommended dose of drip fertigation with 100μm polythene mulching (T1) treatment. Likewise gradual reductions in weed population, superior water use efficiency, nutrient use efficiency and high profitability were observed in all the polythene mulch combination treatments when compared with other treatments without mulch. The study emphasised that adoption of drip fertigation with polythene mulching increases the productivity in coconut, besides ensuring the higher efficiency of water, nutrients and profitability in coconut.

Effect of Drip Fertigation on Yield, Water Use Efficiency, and Nutrients Availability in Banana in West Bengal, India

ABSTRACTField studies were conducted during 2008–2009 and 2009–2010 at the Gangetic alluvial plains of West Bengal, India, to assess the different levels of drip fertigation at variable evaporation replenishment compared to surface irrigation and conventional soil fertilization on yield, water use efficiency, and nutrients availability in plant and ratoon crop of banana. The experiment was laid in an Augmented Factorial Complete Block Design with three replications having three drip irrigation schedules at 50%, 60%, and 70% of cumulative pan evaporation (CPE) and three drip fertigation schedules at 50%, 60%, and 80% of recommended nitrogen, phosphorus, and potassium (NPK) fertilizers with inclusion of conventional surface irrigation at 100% of IW/CPE. The results showed that fruit yield of plant and ratoon crop increased progressively with increasing levels of irrigation water (up to 60% CPE) and NPK fertigation through the drip system. However, maximum fruit yield and water use efficiency of crops was obtained with drip irrigation at 60% CPE with NPK fertigation at 80% of recommended dose. Drip irrigation, as a whole, registered higher fruit yields and water use efficiency with savings of 38.3–41.5% of water compared to surface irrigation. Availability of N, P, and K in soil at vegetative, shooting, and harvesting stages for plant and ratoon crop consistently increased with increasing rate of irrigation water and NPK fertigation through the drip system. Higher availability of macronutrients in soil was recorded with drip irrigation at 70% CPE with 80% of recommended drip NPK fertigation. Overall drip fertigation system improved the available plant nutrients in the soil as compared with traditional surface irrigation.

Impact of fertigation frequency on growth and yield parameters of baby corn (Zea mays) under drip irrigation

The experiments were conducted at the research farm of Water Technology Centre, Indian Agricultural Research Institute, New Delhi during 2010–2011 for three consecutive seasons (October 2010- February 2011, April- July 2011 and August- November 2011) to study the impact of different fertigation frequencies and dripper discharge at different system operating pressures on growth parameters, corn yield and fodder yield of baby corn (Zea mays L.) crop. The study was planned with nine treatments which included dripper discharges at three system operating pressures(0.5 kg/cm2, 1.0 kg/cm2 and 1.5 kg/cm2) and three fertigation frequencies (biweekly, weekly and fortnightly). Growth parameters, viz. number of leaves per plant, plant girth, plant height, leaf area and Leaf Area Index (LAI) of baby corn during different growth stages were measured and recorded. There was a significant (P<0.05) effect of drip fertigation on number of leaves/plant, plant height, leaf area and leaf area index. Maximum number of leaves/plant (15.67), plant girth (57.29 mm), plant height (176.29 cm) and LAI (5.94) were observed under treatment T4 (biweekly fertigation with 1.41 l/h dripper discharge at 1.0 kg/cm2 system operating pressure) at 80 days after sowing (DAS) during second season whereas lower values of number of leaves/plant (11.33), plant height (150.40 cm), plant girth (41.07 mm) and LAI (4.90) were observed at 120 DAS under treatment T4 (fortnightly fertigation frequency with 1.71 l/h dripper discharge at system operating pressure of 1.5 kg/cm2) during third season fortnightly fertigation frequency at system operating pressure of 1.5 kg/cm2 during third season. Yield components of baby corn were not significantly affected by fertigation at different system operating pressures. However, different yield attributes of baby corn were significantly (P<0.05) affected by fertigation frequencies. Biweekly fertigation frequency at par with weekly fertigation schedule while a trend of significantly lower yields were recorded under fortnightly fertigation frequency. Highest yield of baby corn and fodder was recorded in biweekly fertigation schedule with 1.41 l/h dripper discharge at system operating pressure of 1.0 kg/cm2 (22.5 and 633.3 q/ha) followed by weekly fertigation schedule at system operating pressure of 1.0 kg/cm2 (22.0, 619.4 q/ha), respectively during second season. The lowest yields of baby corn and fodder (11.2 q/ha and 454.6 q/ha) were recorded in fortnightly fertigation frequency with 1.71 l/h dripper discharge at system operating pressure of 1.5 kg/cm2 during third season.

Drip Fertigation Program on Growth, Crop Productivity, Water, and Fertilizer-Use Efficiency of Bt Cotton in Semi-arid Tropical Region of India

A field experiment was conducted to assess the effects of drip fertigation with biofertilizers on growth, yield, water, and fertilizer-use efficiency of Bt cotton. The treatments were comprised of drip fertigation with 75, 100, 125, and 150% of recommended dose of fertilizers (RDF) combined with and without biofertilizers as biofertigation, soil application of 100% RDF, and control. Growth, yield attributes, water, and fertilizer-use efficiency of Bt cotton were significantly influenced by drip fertigation treatments. Application of 150% nitrogen (N)–phosphorus (P)–potassium (K) as drip fertigation combined with biofertigation of liquid formulation of azophosmet at 250 ml (1012 cells ml−1) ha−1 was significantly superior over surface irrigation and soil application of 100% NPK and registered the greatest seed cotton yield of 3395 kg ha−1. The soil fertility status was greater under this treatment when compared to surface irrigation and soil application of fertilizers. It is recommended that drip fertigation of inorganic fertilizers in combination with biofertigation be used as a viable technique to realize the yield potential of Bt cotton and sustenance of soil fertility.
