2016 marked the 50th anniversary of the discovery of Hatch-Slack pathway, more popularly known as the C4 photosynthetic pathway in sugarcane leaves. Since then, there had been a significant development in understanding the C4 syndrome and its evolutionary background. C4 photosynthesis produces almost a quarter of the world’s entire primary productivity, despite having merely a few plant lineages to compete with. This clearly depicts the extraordinary capacity of the system to effectively trap carbon and converting it into plant biomass.

The study was carried out during 2013-14 in Meerut district of Uttar Pradesh state to focus on the sugarcane growers regarding impact of knowledge on adoption level of IPM practices. The 80 contact farmers were selected as respondents. The study revealed that the maximum knowledge gap was found to be existing in previous crop residues, crop rotation, hand picking of the insect and their destruction, hot air and water treatment, light and pheromone trap, microbial control, use of natural enemies, resistant varieties, biopesticides/ bio-agents, application and dose of different pest etc.

Preservation of fruits, vegetables, and food are essential for keeping them for a long time without further deterioration in the quality of the product. Solar drying has been used since time immemorial to dry plants, seeds, fruits, meat, fish, wood, and other agricultural, forest products. The aim of the dryer is mainly for the welfare of the marginalized and poor farmers those who can’t afford hi-tech facilities and equipment’s to preserve their agricultural products. Drying of Safed Musli (Chlorophypum boribilianum) in open sun drying require more time and affected its quality.

Bio-rational studies were carried out for predatory pentatomid bugs in soybean with eight treatments. The results found that significantly highest in pentatomid bugs population was found in experimental plots treated with Trap crop (Castor) compare to rest of treatments and at par with NSKE 5%, Neem oil 5% and Intercrop (Sorghum). Secondly better treatment is Pongamia oil 2% except mechanical control and Chlorpyriphos 20EC @2ml/lit.

Bio-rationals studies were carried out for Spodoptera litura in soybean with eight treatments. The results found that significantly reduction in S.litura population was found in experimental plots treated with chlorpyriphos 20EC @2ml/lit compare to rest of treatments. Chlorpyriphos 20EC @2ml/lit was statistically superior in controlling S.litura population and at par with NSKE 5% and Neem oil 5%. Trap crop (castor) found effective in reduction of S.litura population. It was statistically superior compare to rest of the treatments and at par with Pongamia oil 2% and intercrop (sorghum).

Rice is the world’s most important food crop and a primary source of food for more than half of the world’s population. More than 70% of the people of the Arunachal Pradesh are engaged in agriculture. Some traditional lures used in north east region of India like fermented fish, Puntius spp., fermented paste made up of the same, rotten pineapple, rotten crab, rotten frog and a dry fish, Harpadon nehereus were evaluated for the trapping potential against gundhi bug. Maximum numbers of bugs were trapped with rotten frog (11.7) followed by the fermented paste prepared from Puntius spp.

The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum. Potato has high level moisture content, hence it is perishable crop. Blanching is an unit operation prior to freezing, canning, drying in which fruit and vegetables are heated for the purpose of inactivate enzymes; modifying texture; preserving colour, flavour and nutritional value; and removing trapped air. An experiment was conducted to evaluate the effect of pre-treatments on quality of dried potato slices.

Incidence of fruit fly and damage intensity in guava (Psidium guajava L.) in orchards of Eastern India, Ranchi were studied during rainy and winter season in 2013 and 2014 under ICAR-RCER. The observations were recorded on number of flowers and fruits per plants, indicated that flowers and fruit were higher in number in rainy season. However, the weights of fruits were high in winter season as compared to rainy. The number of fruits drop were recorded higher in rainy season about 7.72 % in normal planting and 8.85 % in high density planting in first year study (2013).

A solar photovoltaic insect light trap was developed consisted of 10 Wp SPV panel, 12 V; 7 Ah lead acid battery, charge controller, dusk to down electrical circuit and adjustable stand. As per design calculations the trap was fabricated in the workshop. The performance of solar photovoltaic insect light trap was taken in the farmer’s cotton crop field Vazegaon, Dist. Akola (Maharashtra), for finding out the efficiency of the developed solar insect light trap and insect trapping during night hours.

Four different trap crop plants viz, napier grass, sudan grass, sorghum and bajra were assessed for their potential role as a trap crop in the management of spotted stem borer Chilo partellus (Swinhoe) on maize. Oviposition preference and larval survival tests were conducted in screen house under semi controlled conditions. Results revealed that napier grass was greatly preferred for oviposition over maize but the larval survivability was very poor.

Global climate change is a change in long term weather pattern that characterised by the region of the world. Human activities, especially the burning of the coal and oil, have warmed the earth by increasing the concentration of the heat trapping gases. The impact of warming can be observed in changing weather patterns. Climate change is already affecting human health, ecosystem. Agroforestry has been recognized as a means to reduce CO2 emissions as well as enhancing carbon sinks.
