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 2018-19 and 2019-20. The objective of the experiment was to select suitable variety and appropriate fertility levels for chandrasur crop to achieve higher growth and productivity under Southern Rajasthan conditions. The experiment comprising of twelve treatment combinations of six varieties (HLS-4, GI-2, ULS-2, ULS-6, ULS-9 and ULS-15) and two fertility levels (45 kg N + 30 kg P2 O5 and 20 kg K2 O ha-1 and 60 kg N + 40 kg P2 O5 + 30 kg K2-O ha-1) was laid out in randomized block design (factorial) with three replications. The results show that amongst varieties, maximum height, CGR (30-60 DAS and 60-90 DAS) dry matter accumulation and chlorophyll content of leaves (at 60 DAS) were recorded with variety ULS-15, which remained at par with ULS-2 but significantly superior over rest of the varieties. Branches plant-1 was also found maximum for variety ULS-15, which being at par with ULS-6, remained significantly higher over rest of the varieties. Crop phenology indicated that variety ULS-9 took least days to 50% flowering and days to maturity. Various yields viz. seed, straw and biological yield were maximum for variety ULS-15, which being at par with variety ULS-2 were significantly higher over rest of the varieties. Application of 60 kg N + 40 kg P2 O5 + 30 kg K2-O ha-1 resulted in significantly higher plant height (at harvest), dry matter accumulation (30 DAS, 60 DAS, 90 DAS and harvest), branches plant-1 (at harvest), CGR (30-60 DAS and 60-90 DAS) and chlorophyll content of leaves (60 DAS), compared to 45 kg N + 30 kg P2 O5 and 20 kg K2 O ha-1. However, this fertility level (60 kg N + 40 kg P2 O5 + 30 kg K2-O ha-1) significantly increased days to 50% flowering and maturity. Seed yield plant-1 and 1000 seed weight were increased significantly due to higher fertility level (60 kg N + 40 kg P2 O5 + 30 kg K2-O ha-1 ).
