Effect of emerging new generation fertilizers on yield attribute, yield and profitability of timely sown irrigated wheat (Triticum aestivum L.)
A field experiment was conducted during the rabi season of 2020-21 at Crop Research Centre Meerut, India. The experimental site was sandy clay loam in texture having soil pH 7.9, organic carbon 0.40%, and 216.0, 11.5, 250.0 kg/ha and 0.80 mg/kg available N, P2O5, K2O and Zn respectively. Novel nutrient sources with 12 treatments consisting of control, basal application of recommended 100% NPK (150:60:40) kg/ha, 75% NPK (112.5:45:30) kg/ha + NPK spray 18:18:18 (15 g/l) + NPK Consortia seed treatment (250 ml in 3 litre water 60/kg seed) + Bio-stimulant (625 ml/ha) + Nano N (4 ml/l) + Nano Zn (10 ml/l) in various combinations were attempted on wheat variety HD 2967 in RBD design with three replications. Treatment having 75% NPK + NPK Consortia + NPK spray + Bio-stimulant spray + Nano Zn spray was on par with 100% NPK with biostimulant/nano Zn and significant over RDF in yield and yield attribute. Respective net return 99.45 × 103 ₹ ha-1 Was also better with B:C ratio of 3.0 over RDF.
Stability Analysis for Yield and Yield Contributing Traits in Wheat (Triticum aestivum L.)
Ten parents along with forty-five hybrids (developed by half-diallel) and one check (Lok 1) were evaluated in RBD with three replications in three environments [early sowing (E1), normal sowing (E2) and late sowing (E3)] during rabi 2016-17. Simultaneous consideration of the mean, bi and S2di of the individual genotypes for grain yield per plant showed that among the parents, UP 2672 (22.18), DBW 110 (20.51), GW 451 (20.06) and Raj 4238 (19.29) recorded average grain yield per plant and average stability as the regression was not differing from unity and S2di also non-significant. Average yielding parent GW 451 (20.06) was also average responsive and stable for biological yield per plant and harvest index. Among five best crosses, cross GW 273 × Raj 4238 was average stable over environments. Similarly, three crosses viz., GW 463 × DBW 110, HD 2932 × Raj 4238 and GW 451 × HD 2932 favored for favourable environments.
Weed prevalence, root nodulation and chickpea productivity influenced by weed management and crop residue mulch
Chickpea is a poor weed competitor, and significant yield reduction takes place in presence of weeds. There are limited weed management options available in chickpea. Therefore, we investigated the effect of weed management practices and mulches on weed prevalence, root nodulation and chickpea productivity at Research Farm of JNKVV, Jabalpur (MP), India. A field experiment was conducted on a split-plot and replicated thrice. The main plot was assigned to four weed management viz. pendimethalin 38.7% CS at 1 kg/ha as pre-plant incorporation (PPI), hand weeding at 30 days after sowing (DAS), hand hoeing at 30 DAS and unweeded check, and in subplots four crop residues mulch (CRM), wheat straw (WSM), paddy straw (PSM) and soybean haulm (SHM) each at 5 t/ha and bare land. Results revealed that Unweeded control recorded with maximum weed diversity and biomass followed by hand hoeing at 30 DAS. Imposition of hand weeding at 30 DAS was recorded with the least weeds with lesser weed biomass resulting in higher weed control efficiency (WCE) and better root nodulation, though it was comparable to pendimethalin at 1 kg/ha. Among placed CRM, PSM was recorded with less density, lower biomass with higher WCE and root nodulation which was comparable to WSM but was superior to bare land. Hand weeding at 30 DAS recorded with better yield attributes like pods/plant, seed/pod and seed index lead to higher seed yield (1667 kg/ha) and was at par with pendimethalin at 1 kg/ha. The lower yield attributes and yield was recorded with unweeded control. Among CRM, placement of PSM produced more pods and seeds/pod with a higher seed index resulting in higher seed yield (1554 kg/ha) over others. Thus, placement of PSM at 5 t/ha with one hand weeding at 30 DAS can be recommended for better weed control and higher seed yield in chickpea growing areas of a similar agro-ecosystem.
Genetic Parameters Studies in Segregating Population of Bread Wheat (Triticum aestivum L.)
The experiment of present investigation was conducted to evaluate the 50 wheat genotypes (segregating population lines) along with 5 checks in Augmented Block Design at Research Farm of Department of Genetics & Plant Breeding, School of Agriculture, Lovely Professional University, Phagwara, Punjab. The Analysis of variance for 50 genotypes (F4 segregating population) and 5 check varieties revealed that the treatments are highly significant for days to 50% heading, days to maturity, plant height, number of spikelets per ear, number of grains per spike, spike length. The phenotypic coefficient of variation was greater in magnitude than genotypic coefficient of variation for all the characters under study. High values for both the phenotypic and genotypic coefficient of variation were observed in number of productive tillers per plant. Very high heritability with high genetic advance was observed for characters such as number of tillers per plant, number of productive tillers per plant, 1000-grain weight, biological yield, harvest index.
Effect of nitrogen through organic sources on production efficiency and economics of onion-based cropping systems
The field research was conducted for two years (2015-16 to 2016-17) on clay loam soil at IFSRP, Rahuri (MH), India, to test the organic farming package evaluation of onion-based cropping systems in kharif season. The onion-based cropping sequences were evaluated based on production efficiency, total gross return, net profit and B:C ratio. In the above assessment, the residual impact of 50% N through FYM + 50% N through VC on succeeding rabi season crops was significantly higher than 50% N through FYM + 50% N through NSC and remained at par with 50% N through VC + 50% N through NSC during both the seasons and on the pooled mean. Similarly, all these parameters were significantly higher by direct application of 100% N through organic (50% N through FYM + 50% N through VC) to succeeding rabi season crops on onion-based cropping systems rather than 50% N using through organic and remained at par with 75% N through organic during both the season and on the pooled mean.
