Abstract

Farming systems approach introduces a change in farming techniques for attaining food and nutritional security and for maximizing farm income through optimal utilization of resources by a judicious mix of allied enterprises like dairy, small ruminants like goat and sheep, poultry, piggery, fishery, sericulture etc., with crops suitable for the existing agro-climatic conditions and socioeconomic status of the farmers. Advantages includes Food and nutritional security, enhanced and stable farm income and cash flow through allied components at regular intervals, maintain soil fertility and soil health, environmental protection through effective recycling of waste from animal based enterprises like dairy, goatery, piggery, poultry, etc., and employment generation.

Abstract

Farming system studies in high altitude and tribal area of Srikakulam district of Andhra Pradesh state in East Coast Plain and Hills Agro-climatic zone East coast plains, hot, sub humid to semi arid eco region (S7 Cd 2-5). Agro-ecological region with 915 mm rainfall distribution in 55 rainy days reveals farmer needs to be supported with finance during initial 3 years period @52.23 per cent, 37.46 per cent and 21.75 per cent of recurring cost, respectively. Net returns are getting doubled in first year of intervention itself. The increase income is attributed to increase in income from intervention in paddy crop, introduction of maize crop, feeding of supplement feed to the cattle and also the introduction of Vanaraja back yard poultry birds.

Abstract

Experiments were conducted during Kharif and Rabi seasons of 2015-16 and 2016-17 in farmers fields to study the effect of different agronomic management practices on yield and net returns of rice-rice cropping system in 2 different mandals of Srikakulam district of Andhra Pradesh. The results revealed that yields of rice-rice cropping system were significantly higher over farmer’s practices, by adoption of all the recommended package of practices which includes maintenance of optimum plant population and application of recommended dose of NPK and zinc fertilizers at right stages of the crop growth to both the crops in the cropping system.

Abstract

The central alluvial plains of Gujarat, western India, consist of deposits of north–south flowing rivers from the Aravalli hills. The Gandhinagar and Ahmedabad districts in the state form a part of the Cambay basin and are occupied by Quaternary alluvium comprising mainly of sand, gravel, silt clay, kankar, etc. Direct current (DC) electrical resistivity studies have been carried out at six sites in Gandhinagar and Ahmedabad cities to map ground­water levels and major shallow subsurface geo­electric layers using a 72-electrode resistivity imaging system. Two dimensional (2D) resistivity models and bore­hole data infer a multilayered aquifer system in Ahmeda­bad. The top confined aquifer is at a depth of 22–25 m and the second unconfined aquifer is at a 60–65 m depth. These two aquifers are separated by highly com­pacted clay/clayey sand. For the two locations in Ahmedabad city, the 2D resistivity model suggests 10–15 m variation in the groundwater level. In Gandhinagar, as the survey location is close to the Sabarmati River and the exploitation of groundwater is less than in Ahmedabad, the groundwater table is at shallow level. Further, the resistivity estimates suggest that, at all three locations, the groundwater is moderately saline. The infer resistivity sections are correlated with groundwater level and borehole data
