: An experiment was conducted to study the effect of fertigation levels and schedules on growth, yield and nutrient uptake of tomato under polyhouse. The treatments included 3 fertigation levels (F 1 -60% of RDF, F 2 -80% of RDF, and F 3 -100% of RDF) and 3 fertigation schedules (S 1 -6 equal splits of RD of NPK at every 18 days interval, S 2 -9 equal splits of RD of NPK at every 12 days interval, S 3 -12 equal splits of RD of NPK at every 9 days interval). The results indicated that fertigation of 100 per cent RD of NPK (300:150:150 N, P 2 O 5 , K 2 O kg/ha) in 12 equal splits at every 9 days interval up to 120 DAT was found significantly superior in case of growth, yield attributes and fruit yield of tomato. However, it was at par with 80 per cent RD of NPK (240:120:120 N, P 2 O 5 , K 2 O kg/ha) in 12 equal splits at every 9 days interval up to 120 DAT. Similarly, significantly maximum nitrogen, phosphorus and potassium uptake by tomato plant was registered with fertigation of 100 per cent of RDF and 12 equal splits of NPK at every 9 days interval up to 120 DAT. It was further concluded from the study that fertigation of 80 per cent RD of NPK (240:120:120 N, P 2 O 5 , K 2 O kg/ha) in 12 equal splits at every 9 days interval upto 120 DAT was found to beneficial for higher growth and fruit yield of tomato under polyhouse condition during summer season.
The study was conducted at All India Co-ordinated Research Project on Integrated Farming System, Mahatma Phule Krishi Vidyapeeth, Rahuri to develop integrated farming system model for irrigated conditions of Western Maharashtra. The model was designed for 1 ha area with crop, horticulture, dairy, goat, poultry and vermicompost unit. The integrated farming system model generated system productivity in sugarcane equivalent yield of 375 t ha-1. The gross monetary returns from combination of crop + horticulture + dairy + goat + poultry + vermicompost unit were ₹ 10,55,758 and net monetary returns was ₹ 4, 58, 943 with B:C ratio (1.77). Of this total net returns obtained from integrated farming system model, the per cent contribution of different components were crop (25%), horticulture (4%), dairy (24%), goat (18%), poultry (29%) and vermicompost (7%). Employment generation in integrated farming system model was 422 Man days year-1.
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
SUMMARY :The field experiment was conducted during Kharif 2014 at the Agronomy Farm, College of Agriculture, Kolhapur on sandy clay loam soil with the combined application of chemical fertilizers, FYM and biofertilizers in soybean resulted increased growth and yield. Treatment100 per cent GRDF gave significantly higher plant height (30.68, 55.63, 64.98, 73.90
