Abstract
A field experiment was conducted on loamy sand soils of College Agronomy Farm, B. A. College of Agriculture, Anand Campus, Anand to find out the "EFFECT OF LEVELS OF IRRIGATION, FYM AND FERTILIZERS ON GROWTH AND YIELD OF SUMMER PEARLMILLET (Pennisetum americanum L. Leek) UNDER MIDDLE GUJARAT CONDITIONS" during summer season of the 1999. Twelve treatment combinations comprising three (3) levels of irrigation (0.7 IW/CPE, 0.9 IW/CPE and 1.1 IW/CPE ratios) assigned to main plot and four (4) levels of fertilizers (80 kg N/ha + 10 t FYM/ha, 80 kg N/ha, 120 kg N/ha and 160 kg N/ha) were relegated to sub plots. The experiment was laid out in split plot design with three replications. The results indicated that FYM application markedly increased the growth and yield characters like plant height recorded at 15, 30, 60 DATP and at harvest, number of effective tillers per plant, protein content in grains and grain and straw yields of pearlmillet. Nitrogen application at each levels significantly increased plant height recorded at 15, 30, 60 DATP and at harvest, effective numbers of tillers per plant, protein content in grains, but grain, straw yields and harvest index was remained unaffected. Treatment F1 was found significantly superior than that of treatment F2 in respect of plant height recorded at 15, 30, 60 DATP and at harvest, effective numbers of tillers per plant and protein content in grains. Nitrogen application did not show its significant effect for increased in test weight, effective number of earheads, grain, straw yields and harvest index. Treatment F3 was found significantly superior over rest of the treatments in respect of increased in growth characters of pearlmillet crop, but it was at par with treatment F4 in respect on increased in plant height. Irrigation application at each levels significantly increased plant height recorded at 15, 30, 60 DATP and at harvest, number of effective tillers per plant, number of effective earheads, protein content and test weight of grains, grain and straw yields. Treatment I3 was found significantly superior than that of treatment I1 in respect of plant height, number of effective tillers per plant, effective number of earheads, test weight, grain and straw yields, but it was at par with treatment I2 in respect of plant height recorded at 15, 30, 60 DATP and at harvest, number of effective earheads. While protein content in grains was significantly the highest under treatment I1. Looking to the economics of various treatment combinations I3F3 realized maximum net profit (22143 Rs. /ha) as well as CBR (1:3.04). In nutshell, it would be concluded from the present study that for getting potential production and profit alongwith effective irrigation and fertilizer management in summer pearlmillet under Middle Gujarat Agro-climatic conditions of Anand can be achieved by irrigating crop at 1.1 IW/CPE ratio and fertilized with 120 kg N/ha or 80 kg N/ha + 10 t FYM/ha coupled with 40 kg P2O5 /ha.
