Yield, nutrient uptake and post-harvest soil available Nutrient status of dhaincha as influenced by varied times of sowing and spacings

Abstract

A field experiment was conducted during rabi, 2022-23 on sandy clay loam soils of Tirupati in a split-plot design and replicated thrice. The treatments consisted of four times of sowing viz., Ⅰ FN of October (T1), Ⅱ FN of October (T2), Ⅰ FN of November (T3) and Ⅱ FN of November (T4) allotted to main plots and three spacings viz., 30 cm x 20 cm (S1), 45 cm x 20 cm (S2) and 60 cm x 20 cm (S3) assigned to sub plots. The results of the experiment revealed that among varied times of sowing tried in dhaincha, Ⅰ FN of November sown crop resulted in highest seed and stalk yield, nutrient uptake and lower amounts of post-harvest soil available nutrients. Significantly higher seed and stalk yield, nutrient uptake and lower amounts of postharvest soil available nutrients were observed when dhaincha was sown at a spacing of 30 cm x 20 cm.
