In changing climate scenarios, practically sound and suitable agronomic management options are of utmost need for sustainable crop production. An experiment involving three irrigation scheduling, two mulching, and four integrated nutrient management (INM) treatments was undertaken for consecutive two years at the Research Farm of the Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, India in a split-split plot design with three replicates. This study evaluated the effect of irrigation scheduling, mulching, and INM on the performance of summer groundnut under sub-tropical conditions. Irrigation scheduling, mulching, and INM had a significant influence on growth and developmental parameters, yield attributes, yields, shelling (%), harvest index, quality parameters, and economics. Scheduling irrigation at lower cumulative pan evaporation (CPE) hugely benefited crops through increased pod yield (8.3%) haulm yield (5%), kernel yield (8.4%), oil yield (8.6%), and net returns (12.7%) over higher CPE (100 mm). The use of paddy straw mulch enhanced pod yield, haulm yield, kernel yield, oil yield, and net returns by 8.2, 3.6, 8.3, 9.0, and 13.2%, respectively as compared to dust mulch. Among INM, 75% RDN (recommended dose of nitrogen) + 25% N (FYM) + 60 kg S (gypsum) adjudged significantly better and recorded higher biological yield (16%), net returns (39%), and B:C ratio (16.2%) than 100% RDN. It is concluded that scheduling irrigation at 60 mm CPE along with paddy straw mulch and 75% RDN + 25% N (FYM) + 60 kg S (gypsum) can be adopted for better yield and economics of summer groundnut under sub-tropical conditions. © 2024 Taylor & Francis Group, LLC.
Tillage based Crop Establishment Methods and Zinc Application Enhances Productivity, Grain Quality, Profitability and Energetics of Direct-Seeded Rice in Potentially Zinc-Deficient Soil in the Subtropical Conditions of India

Direct-seeded rice is becoming an alternative to puddled transplanted rice in Indo-Gangetic Plain due to looming water scarcity and shortage of labor. But poor crop establishment and zinc nutrition hinder realizing its full yield potential. Thus, an experiment on direct-seeded rice allocating three crop establishment methods in main plots and five zinc application treatments in subplots was conducted in a split-plot design with three replicates with the aim to evaluate the effect of crop establishment methods and zinc application on productivity, profitability and energetics. Conventional till-wet direct-seeded rice increased effective tillers by 16.89 and 22.98%, panicle length by 5.33 and 10.48% and panicle weight by 7.83 and 13.41% over conventional till-direct seeded rice and zero till-direct seeded rice, respectively. Furthermore, conventional till-wet direct-seeded rice yielded highest grain and straw yield. Basal application of zinc (6.0 kg ha−1) recorded higher grain (4.70–19.50%), straw (3.22–12.92%) and biological yield (3.82–15.51%) over the rest of the treatments. Besides, basal application of zinc (6.0 kg ha−1) also proved profitable and energy-efficient. Therefore, conventional till-wet direct-seeded rice with the basal application of zinc (6.0 kg ha−1) is suggested to realize higher productivity, profitability and energetics of direct-seeded rice in potentially zinc-deficient soils. © 2022 Taylor & Francis Group, LLC.
