SUMMARY

A field experiment to assess the effect of different fertilizer levels on production, productivity, quality and economics of single cut forage sorghum [Sorghum bicolor (L.) Moench] genotypes was conducted at Hisar (Haryana), India during kharif season of 2019. Nine forage sorghum cultivars (SPH 1890, SPH 1891, CSV 30F, CSV 32F, SH 1514, SHH 1513, HJ 513, HJ 541 and CSV 21F) were tested at three recommended dose of fertilizers (RDF) i.e. 75, 100 and 125% RDF in factorial RBD with three replications. SHH 1513 cultivar being at par with SH 1514 and SPH 1890 recorded highest green fodder (GF) dry matter (DM), crude protein yield (CPY) and digestible dry matter yield (DDMY) and net income (531.5, 137.0, 14.24, 74.71 q/ha and 30938, respectively). Highest in-vitro dry matter digestibility (IVDMD) content (56.40%) was observed in SPH 1891 which was on a par with SPH 1890. HCN content was below critical limit in all cultivars. Among RDF levels, significantly higher green, dry, CPY, DDMY, IVDMD and net income (511.6, 133.9, 13.85, 73.02 q/ha, 54.53% and 28080, respectively) were recorded with 125% RDF. Application of 125% RDF has brought an improvement of 18.8 and 8.74 per cent in GFY; 31.4 and 11.1 per cent in DFY; 37.7 and 14.7 per cent in CPY and 37.9 and 13.4 per cent in DDMY over 75% and 100% RDF, respectively. With increased fertilizer levels, the HCN content at 30 days after sowing increased from 75 to 103 µg/g on fresh weight basis but it was less than the critical limit. It is concluded that use of SC forage sorghum hybrids SH 1513, SH 1514 and SPH 1890 and application of 125% RDF was recommended for higher fodder yield, quality and income.

SUMMARY

An experiment was conducted to test the performance of different advance barley genotypes for grain yield and its components under saline soil condition at Barley Research Area, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar during rabi 2018-19. The experiment was laid in randomized block design with three replications with a plot size of 6.9 m². Sixteen advance barley genotypes along with two national checks viz., RD 2794 and BH 946 were evaluated on a natural soil salinity patch having pH of 8.3 and Ece 6 dsm^-1. The variation due to treatment were found to be highly significant for days to heading, plant height, spike length, number of tillers per meter, number of grains per spike, 1000 grain weight (g), biological yield and grain yield, and significant for days to maturity and harvest index. The coefficient of variation was recorded highest for grain yield (17.40) followed by harvest index (11.88) and biological yield (8.36); however, days to maturity (1.52) exhibited lowest variation. Six genotypes namely BH 17-26, BH 17-32, BH 16-44, BH 17-34, BH 17-35 and BH 16-35 produced higher grain yield and also showed better performance for several other yield components. These best performing genotypes may be considered in future breeding programmes intended to develop salt tolerant varieties.

Key words:Barley genotype, performance, saline condition

SUMMARY

To study the effect of different sources of zinc on yield, nutrient content and its uptake by wheat crop, a field experiment was conducted at Research Farm of Department of Soil Science, CCS HAU, Hisar. The experiment site was neutral in reaction, non-saline, low in organic carbon content and texturally sandy loam. The grain and straw yield of wheat increased significantly in all the treatments over control. The highest grain and straw (58.87 q/ha and 74.0 q/ha) yield were recorded with the application of RDF+ 5kg Zn/ha. The maximum concentration (39.70 and 24.0 mg/kg) of Zn and its uptake (233.70 and 178.0 g/ha) by grain and straw was also recorded maximum in treatment receiving RDF+ 5kg Zn/ha.

Key words:Wheat, straw, grain, nutrient uptake and zinc
