Abstract

The drought tolerance of Brassica campestris genotypes viz., KBS-3, KDH-06, KS-101, KLM-40, KLM-1 and KLM-4 was investigated after exposure to drought stress at various growth stages in a pot experiment. Water stress imposed at branch initiation, flower initiation and siliquae formation stages. Data of various biochemical parameters (total chlorophyll content, chlorophyll stability index, total free proline and total oil content) was recorded which revealed significant differences among the various Brassica campestris genotypes for chlorophyll content and proline accumulation. Total chlorophyll content of all the Brassica campestris genotypes declined due to drought stress at all the growth stages. Genotype KBS-3 showed least reduction in chlorophyll content during branch initiation and siliquae formation stage. There was significant increase in osmo-regulating substance proline under water stress and KBS-3 accumulated highest proline. Drought treatment at different growth stages reduced grain yield significantly. Greater reduction in grain yield was observed when stress was imposed at siliquae formation stage. Average yield was found greater in KBS- 3 and least in KLM-4. The better osmoregulation ability under drought stress conditions in KBS-3 proves it as drought tolerant cultivar. The findings of the present research investigation recommended the growing of KBS-3 in the drought prone areas to obtain high economic yield even in adverse condition.

Abstract

An experiment was conducted to study the response of growing media and various concentrations of IBA and cow urine on ischolar_main parameters viz., number of days to ischolar_main initiation, number of ischolar_mains per cutting, ischolar_main length (cm) and survival percentage of the stem cuttings (%). Root formation was significantly earlier in the cuttings treated with RH1C2G2 (RHl = IBA, C2 = 100 ppm and G2 = SoU) and CUCIGI (CU = Cow urine, Cl = 5% and G1 = SoiUess) i.e. 4.67 days than the non treated tomato stem cuttings. Maximum number of ischolar_mains per cutting (27.67) and longer ischolar_main length (8.73 cm) were obtained from treatment RH1C3G2 (RHl = IBA, C3 = 150 ppm and G2 = Soil). All treatments showed a significant increase in all the ischolar_main parameters except survival percentage of the stem cuttings (%).

Abstract

A field experiment was conducted for four consecutive seasons from kharif 2019 to rabi 2020-21 at CSK, Himachal Pradesh, Krishi Vishvavidyalaya, Palampur, Himachal Pradesh (India) to evaluate the effect of different sources of nutrients on growth and productivity of maize-wheat cropping system. The experiment -1 was laid down in Randomized Block Design with three replications having seven treatments viz., T1 - 10t ha -1 FYM + 5% Jeevamrit as basal and at 4 weeks interval, T - 10t ha FYM + 10% Jeevamrit as basal and at 4 weeks 2 -1 -1 interval, T3 - 50% RDN+ 10 t ha FYM+ 5% Jeevamrit as basal and at 4 weeks interval, T4 - 50% RDN+ 10 t ha FYM+ 10% Jeevamrit as basal and at 4 weeks interval T - seed treatment with Beejamrit followed by 5% 5 Jeevamrit as basal and at 4 weeks interval, T - seed treatment with Beejamrit followed by 10% Jeevamrit as 6 basal and at 4 weeks interval, T - recommended NPK through inorganic sources. Application of 50% RDN + 10 7 -1 -1 t ha FYM + 10% Jeevamrit remaining at parwith application of 50% RDN + 10 t ha FYM + 5% Jeevamrit and application of recommended NPK resulted in higher leaf area index and crop growth rate of maize and wheat. -1 Application of 50% RDN + 10 t ha FYM + 10% Jeevamrit proved best to obtain higher relative growth rate of maize, whereas relative growth rate of wheat at 60-90 DAS, 90-120 DAS and 120-150 DAS was significantly higher with Beejamrit + 5% Jeevamrit application. Significantly higher grain yield of maize and wheat, total - yield of system and system productivity of maize-wheat cropping system was obtained with 50% RDN + 10 t ha 1 FYM + 10% Jeevamrit.
