Performance of aromatic rice (Oryza sativa) genotypes as influenced by integrated nitrogen management
(Indian Society of Agronomy, 2014) Lalji Yadav; R.N. Meena
A field experiment was conducted during the rainy (kharif) season of 2010 and 2011 at Varanasi, Uttar Pradesh, to study the performance of aromatic rice (Oryza sativa L.) genotypes as influenced by integrated nitrogen management (INM). The experiment was laid out in split-plot design with 3 replications. The treatments comprised 3 aromatic rice genotypes (‘Pusa Basmati 1’, ‘PRH 10’ and ‘HUR 105’) in main plots and 7 INM practices [100% recommended nitrogen dose (RND), 75% RND + 25% RND as farmyard manure/vermicompost (FYM/VC), 75% RND + 25% RND as FYM/VC] along with biofertilizer blue green algae (BGA)/Azospirillum in subplots. The genotype ‘PRH 10’ recorded significantly higher dry matter (DM) (36.8 g/hill), panicles/m2 (306.9), grains/panicle (133.0), 1,000-grain weight (22.4 g), grain yield (5.19 tonnes/ha), straw yield (7.55 tonnes/ha), total N uptake (103.0 kg/ha), N-use efficiency (57.6 kg/kg) and net returns ((formula presented)53,518/ha) than ‘Pusa Basmati 1’ but were at par with ‘HUR 105’. Among the INM, application of 75% RND + 25% RND as VC + BGA gave significantly highest plant height (105.8 cm), DM (39.5 g/hill), panicle/m2 (321.1), grains/panicle (138.2), 1,000-grain weight (22.7 g), grain yield (5.16 tonnes/ha), straw yield (7.77 tonnes/ha), total N uptake (105.7 kg/ha), N-use efficiency (57.3 kg/kg), net returns ((formula presented)54,376/ha) and benefit: cost ratio (2.0) over other treatments and remained at par with application of 75% RND + 25% RND as FYM + BGA. © 2014, Indian Journal of Agronomy.

Yield and economics as influenced by nitrogen scheduling, weed management and rice establishment methods in transplanted rice (Oryza sativa)
(Indian Society of Agronomy, 2015) Raghubar Sahu; Manoj Kumar Singh; Lalji Yadav
A field experiment was conducted during the rainy (kharif) seasons of 2010 and 2011 at Varanasi, Uttar Pradesh, to evaluate the effect of nitrogen scheduling, rice–establishment methods and weed management on ‘BPT 5204’ rice (Oryza sativa L.) cultivar. The major group of weed species observed in the experimental field were grasses followed by broad-leaf weeds and sedges. Significant reduction in weed biomass was recorded in puddled transplanting as compared to unpuddled transplanting and in butachlor 1.50 kg/ha followed by conoweeding at 20 days after transplanting (DAT) amongst the weed-management treatments. However, in the nitrogen scheduling treatments, significantly lesser weed biomass was recorded in initial reduced dose and delayed nitrogen application (one-fourth at 10 days, half at tillering stage and one-fourth at panicle-initiation stage) than conventional scheduling of nitrogen application (half at basal, one-fourth at tillering stage and one-fourth at panicleinitiation stage). Puddled transplanting resulted in significantly more grains/panicle, panicle length, panicles/hill, grain yield (t/ha), nitrogen uptake and nitrogen-use efficiency, net returns and benefit: cost ratio than unpuddled transplanting and in butachlor 1.5 kg/ha followed by cono-weeding at 20 DAT as compared to the other weedmanagement treatments. An initial reduced dose and delayed nitrogen application (one-fourth at 10 DAT, half at tillering stage and one-fourth at panicle-initiation stage) recorded significantly higher values of yield attributes, yields, net return and benefit: cost ratio than conventional scheduling of nitrogen application. © 2015, Indian Society of Agronomy.
