​Effect of Date of Sowing on Growth, Seed Yield and Economics of Indian Mustard (Brassica juncea) Varieties under Rainfed Conditions

Abstract

Background: Indian mustard (Brassica juncea) is an important rabi crop raised under rainfed areas of Haryana. Optimum time of sowing plays an important role in augmenting the productivity of Indian mustard. There is a need to find out the optimum time of sowing of Indian mustard to overcome the yield gap under present scenario of climatic conditions. Different cultivars may respond differently to different sowing time. The current study aimed to study the effect of date of sowing on growth, seed yield and economics of Indian mustard varieties under rainfed conditions. Methods: In this field experiments were conducted during rabi 2018-19 and 2019-20 at Dryland Agriculture Research Farm, CCS Haryana Agricultural University, Hisar. The experiment comprising of 3 dates of sowing (16 October, 23 October and 30 October) and 4 varieties of Indian mustard (RH 30, RH 406, RH 725 and RH 761) was laid out in split plot design with three replications. Result: Crop sown on 23th October produced significantly taller plants over 30th October sowing. However, yield attributes viz., number of siliquae per plant, number of seeds per siliqua and test weight was successively decreased with delayed sowing of the crop. Seed yield was highest (2499 kg/ha) when sown on 16th October as compared to 23th October and 30th October sowing. Highest net returns (₹ 92674/-) and BC ratio (5.23) was recorded in 16th October sowing over other dates of sowing. Among varieties, RH 725 produced significantly higher seed (2583 kg/ha) and stover yield (7415 kg/ha) over RH 30, RH 406 and RH 761. Variety RH 725 also recorded higher net returns of ₹ 95940/- and B:C ratio of 5.38 compared to other varieties.

Evaluation of Fertilizer-manure Blocks as a Slow Release Fertilizer Formulation for Okra [Abelmoschus esculentus (L.) Moench]

“…Akter et al (2017) reported that the use of fertilizers and organic manures in combination improved crop growth and yield in tomato. Similar results of use of fertilizers and organic manures were reported by Sharma and Singh (2011) in Brassica juncea. Singh et al (2013) recorded the parity of yield between full recommended dose of urea and diammonium phosphate (DAP) and organic matrix entrapped urea and DAP containing ¼ th of the recommended dose.…”

Effect of Sulphur and Zinc levels on growth and yield of safflower (Carthamus tinctorius L.)

“…~ [6] . This was owing to a significant increase in growth and yield attributes with increasing rate of Sulphur application (Santosh Kumar et al, 2009) [16] and Jat and Mehra (2007) [11] also reported an increase in the seed and stalk yield with increasing level of Sulphur.…”

High throughput phenotyping of functional traits and key indices for selection of salt tolerant Mustard [Brassica juncea (L.) Czern & Coss] genotypes

“…The experimental materials consisted of 250 stabilized F 7:8 recombinant inbred lines (RILs) mapping population of Indian mustard developed by the crossing of two contrasting parents; CS 614-1-1-100-13, a salt-sensitive mutant line developed with λ-ray irradiation treatment and stabilized for M 6 generation and CS 56, a national released high yielding salt tolerant variety by ICAR-CSSRI, Karnal (Sharma et al, 2008). These 250 RILs along with parents grown during two consecutive Rabi seasons 2020-21 and 2021-22 under control and irrigation water salinity EC iw 12 dS m À1 in the pots with three replications at Indian Council of Agricultural Research-Central Soil Salinity Research Institute (ICAR-CSSRI), Karnal (29 43'N, 76 58 0 E; 245 m above the average sea level) (Singh et al, 2020).…”
