Maize (Zea mays L.) is one of the most important cereal crop, next to rice and wheat and is used as a food for human and feed for animals. This crop has been developed into a multi dollar business in countries viz. Thiland,
The present study consisted of five land configurations as main plot treatments viz., broadcasting, flat sowing, flat followed by earthing, narrow bed and furrow and broad bed and furrow and four nutrient management practices as sub plot treatments viz., basal dose of NPK + top dressing of N in two splits, basal dose of NPK + foliar spray of N in two splits, basal dose of NPK + N through LCC and basal doses of P and K + N through LCC only, and was laid out in split plot design and replicated thrice. The soil of experimental site was sandy loam in texture, low in organic carbon and available nitrogen, medium in available phosphorous and potassium. The hybrid variety (DKC9144) was sown as per treatment in plant geometry (50×25cm) maintained by thinning. The present investigation revealed that the seed sown in broad bed and furrow accumulated significantly highest nitrogen (grain 1.42% and stover 0.60%), phosphorus (grain 0.33% and stover 0.17%) and potassium (grain 0.38% and stover 1.10%) contents and uptake of these nutrients was also maximum in the same treatment i.e., nitrogen (grain 98.3 and stover 76.5 kg ha -1 ), phosphorus (grain 42.0 and stover 21.4 kg ha -1 ) and potassium (grain 26.5 and stover 140.8 kg ha -1 ) in pooled analysis. Hybrid maize accumulation significantly higher through basal dose of NPK + N through LCC nutrient content when fertilizer nitrogen (grain 1.42% and stover 0.60%), phosphorus (grain 0.33% and stover 0.17%) and potassium (grain 0.38% and stover 1.10%) there by uptake in grain and stover was also higher nitrogen (grain 95.9 and stover 75.3 kg ha -1 ), phosphorus (grain 41.3 and stover 21.1 kg ha -1 ) and potassium (grain 25.8 and stover 138.4 kg ha -1 ) in pooled analysis. Maximum improvement in available status of nitrogen (305.0 kg ha -1 ), phosphorous (18.9 kg ha -1 ) and potassium (244.0 kg ha -1 ) was recorded with broad bed and furrow method followed by narrow bed and furrow system and minimum at broad casting systems over its initial values. In nutrient management system highest increase in available status of N, P and K was recorded in basal dose of NPK + N through LCC followed by basal dose of P and K + N through LCC only over its initial values.
to find out suitable superimposed nutritional doses for increase in production, productivity and economics of chickpea in Central Plain Zone. The treatments consisted seven (7) superimposed doses of sulphur (25 kg ha -1 ), Boron (1.0 kg ha -1 ), FYM (5.0 t ha -1 ) used a individually, Rhizobium culture + FYM, Sulphur+ Boron, Sulphur + Boron + FYM, Sulphur + Boron + FYM + Rhizobium in combination along with NPK (20:60:20 kg ha -1 ) doses compared with only NPK (20:60:20 kg ha -1 ) dose (control treatment). The experiments were laid out in Randomized Block Design, replicated three times. The response of above treatments is analyzed on growth parameters, yield attributes and yield as well as quality of chickpea, variety KWR-108. The superimposition effect of sulphur, Boron, FYM and Rhizobium species along with NPK doses in different treatment exhibited significant response is terms of increasing grain yield to the tune of 23 percent to 62 percent compared to control treatment. Among different treatments superimposed doses of NPK (20:60:20 kg ha -1 ) + Sulphur (25 kg ha -1 ) + Boron (1.0 kg ha -1 ) + FYM (5.0 t ha -1 ) + Rhizobium inoculation treatment recorded maximum grain yield (1348.14 kg ha -1 and 1873.21 kg ha -1 ), Nitrogen content (3.34% and 3.37%), Phosphorus content (1.46% and 1.47%), Potash content (0.65% and 0.67%), Sulphur content (0.61% and 0.63%) and Boron content (57 ppm and 58 ppm) in grain during 2014-15 and 2015-16, respectively compared to NPK only (control) treatment, which recorded lowest grain yield (1000.73 kg ha -1 ) and 1154.54 kg ha -1 ), Nitrogen content (3.18% and 3.20%), Phosphorus content (1.23% and 1.25%), Potash content (0.47% and 0.49%), Sulphur content (0.43% and 0.45%) and Boron content (41 ppm and 42 ppm) in grain during 2014-15 and 2015-16, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
