Description |
A field experiment was conducted during kharif 2002 on sandy clay loam soil at the Agricultural College Farm, Bapatla of Andhra Pradesh to find out the influence of nitrogen sources and planting methods on productivity and quality of rice varieties. The experiment was laid out in split plot design replicated three times with twenty treatment combinations involving two methods of planting (Direct seeding and transplanting) and two rice varieties (BPT 8024 and MTU 2077) as main treatments and the sub plot treatments consisted of five nitrogen management practices (No nitrogen, 100% recommended nitrogen through fertilizer, 100% recommended nitrogen through organic source viz., FYM, 50% recommended nitrogen through fertilizer + 50% recommended nitrogen through FYM and 100% recommended nitrogen through fertilizer + 25% recommended nitrogen through FYM). The results indicated that neither the two planting methods nor the two varieties had any significant affect on the growth as well as quality parameters of rice. The interaction affect between the planting methods and varieties was also non significant. Among the different nitrogen management practices, combination of 100% recommended nitrogen through fertilizers and 25% recommended nitrogen through FYM (RDN100 + M25) produced taller plants, increased number of tillers, dry matter accumulation, panicle length, number of panicles m-2 and number of filled spikelets per panicle of rice crop which was superior to other nitrogen management practices except RDN100 and 50% recommended nitrogen each through fertilizers and FYM (RDN50 + M50-). Application of RDN100 + M25 has resulted in the highest 1000-grain weight, grain and straw yield as well as harvest index and nutrient uptake. Head rice recovery, volume expansion ratio, protein content and amylose content were the highest with RDN100 + M25 which was however, comparable with RDN50 + M50 and 100% recommended nitrogen through fertilizer alone, but distinctly superior to 100% recommended nitrogen through FYM. From the present investigation, it can be concluded that transplanting method proved significantly not superior to direct seeding in respect of growth and yield of rice. Productivity and quality of rice in respect of nitrogen sources exhibited significant variations due to application of 100% recommended nitrogen through fertilizer and 25% nitrogen through FYM and closely followed by 50% N each through fertilizer as well as FYM. |
