Livestock is the integral component of Indian agriculture since time immemorial. Its contribution to national economy through milk, meat, wool as well as farmyard manure is enormous. India has the largest number of livestock, representing over 17% of the world. Among four important species of livestock, cattle represent over 43% of the population followed by buffaloes (19%), goats (26%) and sheep (10%). The share of livestock reared is highest in marginal followed by small and semi-medium land holders implying that marginal holders and small land holders are playing seminal role in development of livestock sector in country. The productivity of livestock and growth of animal husbandry are closely linked with the biomass and quality of forages. Currently there has been radical change in realising the importance of forages in integrated farming system, crop diversificati...

Gas chromatography of leaf extracts revealed the presence of saturated hydrocarbons ranging from C 14 to C 29 in varying numbers and concentrations. These hydrocarbons elicited varied synomonal responses from the parasitoid. The quantity of individual hydrocarbons varied from 72 to 34,940 ppm in the vegetative period and from 4 to 46,170 ppm in the flowering period. Hexane extracts obtained during the flowering period showed a greater synomonal response compared with those obtained during the vegetative period. A better response observed for certain varieties of tomato at a particular period could be due to the presence of higher concentrations of favourable hydrocarbons relative to unfavourable ones. Synomonal activity seems to be associated mainly with tricosane, heneicosane, pentacosane and hexacosane during the vegetative period and with heneicosane and hexacosane during the flowering period. In the vegetative period, the tomato variety To-Pant-T4 elicited the highest activity as well as parasitism at the lowest concentration of 25,000 ppm, which was higher than other varieties at all concentrations. Varieties To-BT-116-32, To-BT-20-2-1 and To-Pant-T3 in the vegetative period and To-Selection-15, To-Selection-32 and To-BT-22-2-1 in the flowering period elicited higher responses than the other varieties. To-BT-20-2-1 elicited a maximum response in the flowering period, which may be due to the presence of higher relative quantities of tricosane, heneicosane and hexacosane. In view of these findings, tomato varieties with favourable semiochemicals could be exploited in an integrated pest management programme to enhance the effectiveness of the egg parasitoid T. chilonis against the fruit borer Helicoverpa armigera (Hb).

Among all the techniques, agroforestry was recognized as one of the important means to reduce CO2 emissions as well as enhancing carbon sinks. Agroforestry provides unique opportunity to combine the twin objectives of climate change adaptation and mitigation. In India, area under agroforestry was estimated at 25.3 m ha, which can further be increased up to a considerable level. Recent studies under various agroforestry systems in diverse ecological conditions emphasized that agroforestry systems increase and store carbon stocks in above ground biomass and in soil and also has an important role in increasing livelihood security and reducing vulnerability to climate change. In India carbon sequestration potential of agroforestry systems is estimated between 0.25 – 19.14 and 0.01 to 0.60 Mg C/ha/yr for tree and crop component, respectively. The contribution of agroforestry in soil carbon sequestration varied between 0.003 to 3.98 Mg C/ha/yr. The total C sequestered in each component differs greatly depending on region, types of -species, -system, -site quality, and previous land-use. The review indicates that agroforestry systems in addition to accumulate and sequester carbon, provide an excellent opportunity to increase the tree cover to a level of 33% of the total geographical area of the country as desired by the National Forest Policy.

This paper presents data from three paired scaling-up initiatives to compare the benefits of landscape-based interventions over individual plot-level interventions using evidence generated in the Indian semi-arid tropics. A range of soil and water conservation interventions were implemented in a decentralized manner following the landscape-based approach. The plot-level approach focused only on balanced fertilizer application and improved crop cultivars while the landscape-based interventions primarily addressed moisture availability, which was the key to reducing risks of crop failure besides aiding productivity gain and enhanced land and water-use efficiency. These interventions have additionally harvested 50–150 mm of surface runoff and facilitated groundwater recharge in 550–800 mm rainfall zones. Individual plot-level interventions also improved the crop yield significantly over the control p...

Nearly 70% of the population of Bundelkhand is dependent on agriculture and allied sectors for its livelihood. A National Sample Survey report of 2017 shows that the per capita income in Bundelkhand is nearly ₹25,000, far below the national average (₹103,000) and those of Uttar Pradesh (₹43,800) and neighboring Madhya Pradesh (₹56,200) and Rajasthan (₹76,900). Given that strategies that focus on transforming agricultural and allied sectors are key to improving livelihoods of rural populations, the Government of India laid the pathway for doubling farmer’s incomes by 2022.

The haveli system was the lifeline of the region for water security for the last 300 years. Farmers (~1–5%) situated at the upstream of the landscape were harvesting surface runoff in their fields during monsoon by constructing earthen embankments along with provision to drain out water after receding of the monsoon. Farmers traditionally cultivated only during the post-monsoon period, using residual soil moisture along with supplemental irrigation from shallow dug wells. However, this system became defunct due to apathy and poor maintenance. The traditional design of the havelis were also often malfunctioning due to new rainfall patterns and storm events. Farmers are facing new need for haveli rejuvenation and the traditional design and knowledg...

Therefore, it is necessary to study the allelopathic impact of these tree species on understory crops. Hence, present study was conducted to assess the allelopathic effect of aqueous leaf extracts of A. cadamba and M. dubia on Triticum aestivum (wheat) under laboratory conditions. Study consisted of seven concentrations of aqueous leaf extracts of A. cadamba and M. dubia (0.5, 1, 2, 3, 4, 5 and 6%) along with a control (0%). The results showed that lower concentrations (0.5, 1 and 2%) of aqueous leaf extract of A. cadamba had no allelopathic impact, however higher concentration (6%) showed maximum inhibitory allelopathic impact on seed germination (90%). Higher concentrations of M. dubia leaf extract also exhibited allelopathic effect on seed germination and resulted in minimum (63.3%) germination at 6% concentration. Similarly, ...
