| dc.description.abstract | A field experiment entitled Nutrient management in rice-wheat cropping sequence was made during 1991-92 at the Birsa Agricultural University Farm, Ranchi on sandy loan, acidic (pl 6.2) soil having 0.37% organic carbon, 287,25 kg ha N, 26.3 kg ha 2205. 198.23 kg ha K₂0 and 6.32 ppm sulphur. The experiment was conducted in randomized block design with 8 treatments replicated 3 times. The fertilizer was applie 40 kg + 30 kg Pas + 20 kg K₂O + 20 kg S per hectare and crop residues (Gram) was incorporated 1 q ha before start of the rice experiment (kharif) while rice straw was incorporated 05 q ha after harvest of rice crop (before sowing of wheat crop). The result revealed that application of nitrogen is a must for getting the higher yield of both crops (rice wheat) taken in sequence. The treatments, where nitrogen was applied, had 117.19% and 32.5% more grain yield (rice and wheat respectively) as compared to those ones where nitrogen was not applied. Application of phosphorus, potassium, sulphur and crop residues did not enhance grain yield if nitro gen application was omitted from the treatments. However, due to application of sulphur a decrease in ph was observed making the soil more acidic. Upland rice receiving recommended dose of NPKS and crop residues recorded the maximum cost of cultivation (Re 3019 ha generating the highest gross return (Rs 6050 ha) with the maximum net profit (Rs 3031 ha). In wheat, where NKS and crop residues were applied recorded maximum net profit (Rs 1487 ha-¹). | |
