Sustainability in Rainfed Maize (Zea mays L.) Production Using Choice of Corn Variety and Nitrogen Scheduling

Abstract

Interestingly more than 50% of the world’s area is rainfed and approximately 80% of maize is cultivated under rainfed condition where selection of cultivar and management of nitrogen have major impact on production. The aim of this study was to evaluate the growth, phenology, yield and quality parameters of maize as influenced by variety and nitrogen scheduling under rainfed condition. For this, a field experiment having two factors was laid out in a factorial randomised block design and replicated three times. The first factor was variety, i.e., V1 (JM 216) and V2 (JM 218), and the second was six nitrogen scheduling, i.e., N1 to N6, in which nitrogen splitting was done based on 30-years of average rainfall data. Variety JM 218 and N5 [40 kg N as basal followed by (fb) 2 splits of 40 kg N and 38.8 kg N at 30 and 52 days after sowing (DAS) and 1% N foliar spray at 40 DAS] nitrogen scheduling were found promising under rainfed situation because it recorded maximum value of growth parameters, yield attributes, grain yield and quality parameters (protein, mineral and dickson quality index). Thus, it can be inferred that JM 218 and N5 nitrogen schedule would be a better choice than alternative options.

Phenolic Profile and Antioxidant, Anticholinergic, and Antibacterial Properties of Corn Tassel

“…The various uses of corn as food, fodder, animal feed, and lately biofuel have further made it a more favorable and valuable crop. Worldwide, on 197.20 million hectares of land, 1148.48 million metric tonnes of maize were harvested, on average [ 1 ].…”

Effect of Foliar Application of Boron, Zinc and Manganese on Dry Matter Accumulation, Total Tuber Yield and Economic Feasibility of Potato (Solanum tuberosum) cv. Kufri Chipsona – 1 under Gwalior Climatic Conditions

“…Tubers yield/ha were recorded between T1 (16.59 t/ha) and T8 (30.57 t/ha). Data indicated total tubers yield highest in T8 (30.57 t/ha), followed by T7 (29.88 t/ha) that are comparable with [6,[24][25][26] who showed that 'Spunta' cv. produced higher unmarketable tuber than 'Diamant' and 'Cara'.…”

“…The highest yield was observed when supplying Zn plus Mn foliar combination one time every two weeks (18.32 . 'Spunta' cv produced the highest yield of marketable tuber when supplied with Zn plus Mn foliar combination one time every two weeks, while 'Cara' cv recorded the least yield of marketable tubers when no Zn plus Mn foliar combination was supplied" [6,24,26]. As well as [7, 25,27] stated that "potato is relatively sensitive to Zn deficiency.…”

“…Because potatoes produce a large amount of crop in a short growing season, they are regarded as a crop that requires a lot of nutrients. Crop development and growth depend heavily on balanced nutrition [6], with 17 key nutrients needed for plant growth and reproduction. When it comes to nutrients, some are needed in relatively high quantities (known as macronutrients) and others in smaller amounts (known as micronutrients).…”

Potentiality of Sustainable Maize Production under Rainfed Conditions in the Tropics by Triggering Agro-Physio-Biochemical Traits Ascertained from a Greenhouse

“…Rainfed agriculture is widespread throughout the world, including tropical regions, with around 80% of cropland under rainfed cultivation [ 1 ]. Maize ( Zea mays ) is a major food, forage, and fuel crop that is grown on about 207 million hectares of land in over 110 countries [ 2 ], with more than 80% of the area being rainfed [ 3 ]. As a tropical country, Thailand has a majority area of maize under a rainfed system [ 4 ], about 78% [ 5 ].…”
