A field experiment was conducted during 2017-18 to examine the impact of integrated nutrient management on growth parameters of broccoli (Brassica oleracea L. var. italica) cv. Pusa KTS-1. The experiment comprised of twelve treatments consisting of different combinations of organic and inorganic fertilizers. The experimental field was laid out in randomized block design (RBD) with three replications. All variable parameters regarding yield behaviour were significantly influenced by integrated nutrient management practices. Results indicated that combined application of 80% NPK + 2 t/ha vermicompost gave the significant effect on yield attributing parameters viz., head diameter (21.33 cm), number of spear per plant (13.00), head weight (332.33 gm) and yield (162.84 q/ha) as compared to other treatments.
In late December 2019, patients suffering from viral pneumonia due to an unidentified microbial agent were reported in Wuhan, China. From genomic surveillance of clinical samples collected from patients with viral pneumonia in Wuhan, China, a novel coronavirus (termed 2019-nCoV) has been identified. To combat coronavirus pandemic infection, mushroom possessing high nutritional and medicinal values with enriched source of proteins, vitamins, crude fibers and minerals can be used for enhanced human's immune systems and improve quality of life specially when the patients becomes weaker due to Coronavirus (Covid-19) infection. In China, more use of mushroom was promoted in 2002-2003 when, there was an epidemic of Severe Acute Respiratory Syndrome (SARS-CoV) coronavirus that emerged in Guangdong, southern China, in November, 2002 and resulted in more than 8000 human infections and 774 deaths in 37 countries during 2002-03 and Middle East Respiratory Syndrome (MERS) corona virus (MERS-CoV) which was first detected in Saudi Arabia in 2012 and was responsible for 2494 laboratory-confirmed cases of infection and 858 fatalities since September, 2012, including 38 deaths following a single introduction into South Korea. Thus, use of mushroom in daily life can directly benefit to the human health and fitness in fighting against corona virus infection.
The present study was carried out at ICAR-National Research Centre on Litchi, Muzaffarpur during 2014-2017 for sustained productivity, profitability, employment generation and soil health. Four different models comprised of rain water harvesting, fish culture, and intercropping of annual and vegetable crops with litchi (Litchi chinensis Sonn.) + banana and litchi+papaya in different combinations on pond dykes. Rain water accumulated in the ponds during rainy season with the storage capacity (7.29 million litre water) varied from of 1.62-2.16 million litre of water per pond. Among different models, model 1 recorded the highest total system productivity in terms of LEY (25.49 t/ ha), production efficiency (140.67 kg/ha/day), net return (₹ 159950/ha) and system economic efficiency (438.23 ₹/ ha/day). Sustainable value index (SVI) among the models varied due to different component and expressed 2 to 3 time’s higher value than existing system. Model 1 recorded highest SVI (0.78) and existing model (0.25) recorded lowest. Relative production and economic efficiency of the different models were also computed over the crop based existing system and value ranged from 521.72 and 67.64 in model 4 to 529.38 and 116.15 in model 1, respectively. Integration of fish, fruits, vegetable and crop component in the system showed greater employment opportunity and it was almost double than the crop based existing system. The highest employment generation was observed in model 1 (331 man-days/ha/year) as compared to existing system (150 man-days/ha/year). Marked improvement in soil health status (pH, EC, soil organic carbon and NPK) was observed as compared to initial soil status after three years of study.
The modified triple test-cross analysis was applied to estimate additive (D), dominance (H) and epistatic component of genetic variance for ten quantitative traits of tomato.Three testers, BT-17 and PS-1 and there hybrid (BT-17 x PS-1) were crossed to 15 inbred lines to develop the experimental material.Overall epistasis was important for days to flowering, number of flower/cluster and number of fruit/cluster.Significant estimate of both additive and dominance component were observed for all the characters, except number of branches per plant, number of fruit per cluster, fruit set per cent and number of fruit per plant for additive and plant height, number of branches per plant, number of fruit per cluster, fruit set per cent and number of fruit per plant for dominant component.The F value was positive and significant for number of branches per plant, number of fruit per cluster, number of fruit per plant and fruit size showing is odirectional nature of dominance.Significant of additive components and F parameter showing increasing effect on the characters, indicates that pedidree selection would be effective for improvement of such traits.
