RESUMEN
A field experiment was conducted during Rabi 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) to study the ”Effect of Nitrogen Rates and Foliar Spray of Urea Application and Nano Urea on Yield and Economics of rabi Maize (Zea mays L.)”effect of three nitrogen rates (50%, 75% and 100% RDN ) and three foliar spray of urea viz 20000 PPM (2%) and nano urea viz 2000 PPM (2 ml/L) and 4000 PPM (4ml/L) application on yield and economics of rabi maize (Zea mays L.). The soil of experimental plot was sandy loam texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.28%), available N (225kg/ha), available P (19.50) kg/ha) and available K (92 kg/ha). The experiment consists of 10 treatment, each being replicated thrice and laid out in Randomized Block Design. The results of present investigation revealed that the highest Grain yield (6.41 t/ha), Stover yield (8.65 t/ha), Harvest Index (42.58), Maximum gross return (INR 1,28266.67), Net return (81,682.75) and B:C ration (1.75) under 100% RDN +4000ppm (4 ml/l) spray of nano urea.
RESUMEN
A field experiment was conducted during Rabi 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) on the topic “Effect of row ratio on growth and yield of wheat and mustard intercropping system”. To study treatments consisting with row Proportions with wheat and mustard intercropping. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 8.0), low in organic carbon (0.28 %), available N (225 kg/ha), available P (19.50 kg/ha) and available K (92 kg/ha). There were 8 treatments each being replicated thrice and laid out in Randomized Block Design. The results revealed that treatment 1 (Sole wheat cropping) recorded significantly higher Plant height (89.4 cm), plant dry weight (16.15 g), number of effective tillers/m2 (634.01), number of grains/spike (52.80), grain yield (4.02 t/ha), straw yield (6.73 t/ha) of wheat and treatment 2 (Sole mustard cropping) recorded significant and higher Plant height (120.50 cm), plant dry weight (34.18 g), number of siliqua/plant (210.47), number of seeds/siliqua (22.90), test weight (3.66 g), seed yield (1.27 t/ha), stover yield (2.65 t/ha) and Harvest index (32.33 %) in mustard.
