Field experiment was conducted to study the insect pest complex and their incidence on cauliflower during rabi season of 2021-2022 in the Entomological farm, SASRD, Medziphema, Nagaland. Fourteen insect pests were found to attack the crop at different stages of crop growth. Out of these, Green peach aphid, Myzus persicae and Cabbage butterfly, Pieris spp. were considered as major insect pests of cauliflower. The peak population of Green peach aphid (8.74 aphids/leaf) and Cabbage butterfly (4.10 larva /plant) was observed on 17th December and 12th February, respectively. The population of Myzus persicae showed a non-significant negative relation with maximum (r = -0.320) and minimum (r = -0.311) temperature, while positive relation with maximum (r = 0.028) and minimum (r = 0.249) relative humidity as well as rainfall (r = 0.021). The population of Pieris spp. showed a non-significant negative correlation with maximum (r = -0.484) temperature, whereas a significant negative correlation was observed with minimum (r = -0.550) temperature. Correlation of relative humidity with the incidence of Pieris spp. exhibited a non-significant negative correlation with maximum (r = -0.078) and minimum (r = -0.162) relative humidity, while rainfall exhibited a non-significant positive correlation (r = 0.235).

Pulses are of paramount importance in Indian agriculture next to cereals and oilseeds in terms of acreage, production and economic value. Pulses are important sources of protein in a vegetarian diet, especially in India, where a large part of population is vegetarian and protein malnutrition is rampant and has not yet received adequate attention for micronutrient fertilization. To reduce the demand and supply gap, government of India launched various programs in pulses. Still, prime attention is required to meet the food security challenges, especially in case of pulse sector. In order to increase the pulse productivity while sustaining at high levels, greater attention on nutrient managements including micronutrients are among the promising technologies in pulse production. Among those micronutrients, zinc (zn) and molybdenum (Mo) are of major concerns. Mo acts as a cofactor for the enzymes namely nitrogenase and nitrate reductase, which take lead roles in bio-logical fixation and subsequent assimilation of nitrogen in legumes. Thus, Mo plays an important role in metabolism and biosynthesis of nitrogen into protein. Besides this, it facilitates the various physiological and biochemical process in pulses. Application of Mo enhances the bioavailability of other essential nutrients to crops. Plants subjected to zinc deficiency display alterations in the activity of many enzymes and decreased protein synthesis. Foliar spray of nutrient fertilizers at the critical stages of rainfed condition, application of micronutrients and secondary nutrients has been great focus in boosting up pulses productivity in India. Thus, this article represents critical review on constraints of low pulse productivity, role of Zn and Mo fertilization to gear up the present pulses productivity to larger extent while sustaining the productivity of pulses in India.

Mahua flower is an important non-timber forest produce and has a great importance in tribal communities. It is frequently under appreciated due to poor quality brought on by poor storage procedures. Hence, the present study was conducted to assess the effect of various doses of gamma irradiation (0.25, 0.50, 0.75, and 1.0 kGy) on nutrient composition of dried mahua flowers stored at ambient temperature. Exposure of mahua flowers to irradiation improved the storability and preserved its nutritional value even after a year of storage. Nutrient composition of the flowers remained almost similar after 1 year storage with 0.25 kGy and 0.50 kGy doses of irradiation, while an increase in moisture and protein, decrease in ash and crude fiber content was observed in dried mahua flowers treated with gamma radiation doses of 0.75 and 1.0kGy. Among the bioactive compounds the phenol content was maintained at the same level with 0.25 kGy dose and the total flavonoid content was observed to be enhanced with all the four doses of irradiation. However, the antioxidant and carotenoid content of the flowers were found to be negatively affected by irradiation. The initial antioxidant content (1076.11 µg/100g) was reduced to 54.30 µg/100g after one year of storage. It can be inferred that modest doses of gamma irradiation (0.25 kGy and 0.50 kGy) might enhance the storability and retain quality attributes of dried mahua flowers and can be employed as an effective postharvest management approach for preserving and prolonging the shelf life of mahua flowers.

India is the world’s top producer and consumer of pulses. The area under pulse crop is increasing continuously but productivity is decreasing over years. Reduced production is caused by a lack of care, an uneven fertilizer application and the emergence of physiological problems, particularly inefficient assimilate partitioning, poor pod development, excessive flower abscission due to the nutrient stress. Foliar nutrition is an efficient way of supplementing the available plant nutrients when they lack in the soil. Organic fertilizers are mainly used to stimulate growth by providing proper nutrients at the right dose and proper stage of the crop growth. Liquid organic manures are the source of macronutrients, necessary micronutrients, required amino acids, growth promoting factors and certain beneficial microorganisms. There is an opportunity for increasing pulse yield and quality by raising soil fertility and productivity by increased ability of conservation of soil organic carbon and soil moisture.

An experiment was conducted at Shivapuri, Chidambaram, Tamil Nadu, India for estimation of genetic variability parameters. The genetic investigation studies in 46 brinjal genotypes estimated genetic variability parameters namely Phenotypic (PCV) and Genotypic (GCV) coefficient of variation, range, mean, genetic advance and heritability. The ANOVA due to genotypes is found to be significant indicating the genotypes under study are diverse. The PCV for all characters were slightly higher than GCV, indicating the presence of little environmental influence. The high values of heritability and GAM for yield per plant and yield related traits like fruit weight, fruit length, number of fruits per plant and number of fruits per cluster suggest the inclusivity of these genotypes for yield improvement in brinjal. Further, the genotypes could be studied for genetic and specific combining ability, in-order to include valuable landraces in location specific and objective specific breeding programs.

The experiment was framed in CRD (Completely Randomized Design) and repeated 3 times with 7 treatments and an uncoated treatment. The results obtained from the current investigation on biochemical changes in quality parameters the fruits treatments with cling film (T7) had minimum TSS, TSS : Acid ratio, reducing sugar and total sugar content with maximum acidity content while fruits coating with paraffin wax (T6) and cling film(T7) had maintaining of chlorophyll content up to 15th days of storage under ambient condition.","PeriodicalId":36141,"journal":{"name":"Environment and Ecology Research","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135688602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Oliseed crops (Brassica napus and B. juncea) are the most important rabi oilseeds in India, following groundnut in the oilseed economy. The present study aimed to examine differential response of culture filtrates of phosphate solubilising microbes enriched with bonemeal to improve seed germination and seedling vigour of mustard. The culture filtrates of each organism was prepared by using PVK broth medium and using bonemeal as a P-source which again supplemented with chlorides and sulphates, respectively. The seeds of mustard were treated in each culture filtrate and kept overnight and then next day arranged in germination paper containing 200 seeds each. Seeds were soaked in sterilized water only serve as control. In experimental results maximum P-solubilization efficiency was shown by A. niger followed by B. subtillis, B. amyloliquifaciens, V. laecani and T. harzianum in broth. As the P-solubilization efficiency of microbes also increases gradually increases doses of bone meal. It is also found that the seed treated with culture filtrate obtained from Cl- and SO42- media containing 5g and 15g of bone meal which were inoculated with organisms shown very reliable progress which was recorded on germination percentage, seedling vigour, seedling length and root length.
