Abstract:
A field experiment was conducted at the Instrumental Farm (Agronomy), Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur during rabi, 2021-22. The study was conducted with an objective to study the effect of various fertility levels and row spacing on nutrient content and uptake of chandrasur. The soil texture of the experimental field was clay loam, medium in available nitrogen and phosphorous, high in available potassium and slightly alkaline in nature. ULS-15 variety of the crop was used for the research using factorial randomized block design replicated thrice with twelve treatment combinations of four fertility levels (40 kg N + 20 kg P₂O₅ ha^-1, 50 kg N + 30 kg P₂O₅ ha^-1, 60 kg N + 40 kg P₂O₅ ha^-1 and 70 kg N + 50 kg P₂O₅ ha^-1) and three row spacing (30, 45 and 60 cm). Result of experiment revealed that significantly higher nutrient content in seed and straw was recorded with application of 60 kg N + 40 kg P₂O₅ ha^-1 but was found at par with 70 kg N + 50 kg P₂O₅ ha^-1. Different row spacing has no effect on the N, P, K content in seed as well as in the straw but did effect on the nutrient uptake by the seed and straw of chandrasur. The N, P and K uptake has been found increasing with the narrowest row spacing up to 30 cm) and further increasing available space per plant by adopting wider row spacing up to 60 cm there was a significant reduction in the nutrient uptake.
