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.
A comprehensive review on biological activities of Bunium Persicum.
Bunium Persicum is a herb of the Umbelliferae family expand in separate regions of Asia. It is a perennial herb, 30cm to tall 80cm height and its flowers are small, white in color. Bunium Persicum has consequential therapeutic, antioxidant and antimicrobial effects which appropriate its high prospective use in the therapeutic and food industry. In conventional medicine, uses of this plant in remedy or enhance digestive and urinary disorders, glaucoma, corpulence and increasing breast milk. Bunium Persicum recognize some inflammable compounds, limonene, gamma-terpinene, p-cymene, β-pinene, α-pinene, cuminaldehyde, and myrcene. Because of the reality that Bunium Persicum is generally used in diet as a flavoring agent, there is no vital concern regarding the virulent effects of this plant.
Growth and variability in sorghum production in Bhilwara district vis-à-vis Rajasthan
The purpose of this research is to look at the variations in sorghum crop area, production, and productivity in Bhilwara district and Rajasthan state. The investigation was carried out using secondary data. For the years TE 1990-91 to TE 2019-20, data was gathered from a variety of government publications and websites. The compound growth rate, coefficient of variation (CV) and instability index, effects of area, productivity and their interactions towards increasing production are also computed. Sorghum crop in Bhilwara district and Rajasthan state grew annually with compound growth of 1.40 and -0.36 percent in area, 5.65 and 2.63 percent in production, and 4.20 and 3.07 percent in productivity. The instability in terms of Cuddy Della Valle Index in the sorghum area, production, and yield in Bhilwara district was found to be 11.85, 42.99, and 38.62 percent, respectively, while it was found to be 7.27, 19.78, and 16.56 percent in Rajasthan. The relative contribution of yield, area, and their interaction (area and yield) in Bhilwara district was 79.60, 19.46, and 0.94 percent, while in Rajasthan it was 250.25, -163.80, and 13.55 percent, respectively.
