abstract = {The deficiency of sulfur (S) as a constraint to crop productivity in irrigated, intensified systems has long been recognized (Kanwar 1972; Pasricha and Fox 1993; Singh 2001). A recent survey of farmers? fields in the Indian semi-arid tropics (SAT) demonstrated that the deficiency of S, as a constraint to crop production and productivity, is also equally widespread in the rainfed production systems (Rego et al. 2007; Sahrawat et al. 2007). The results of this research further showed that soil testing was effective in diagnosing S deficiency; and the crops grown on farmers? fields with calcium chloride extractable-S levels of less than 8-10 mg kg-1 soil responded positively to the application of sulfur (Rego et al. 2007).},

Results of analyses of soil samples from farmers? fields in several districts of Andhra Pradesh, Karnataka, Tamil Nadu, Rajasthan, and Madhya Pradesh states and Junagarh district, Gujarat, showed that almost all farmers? fields had low organic carbon (C), low to moderate available phosphorus (P), and generally adequate extractable potassium (K). However, the widespread deficiencies of sulfur (S), boron (B), and zinc (Zn) were most revealing; their deficiencies varied with nutrient, district, and state. On-farm trials conducted during three seasons (2002?2004) in three districts of Andhra Pradesh showed significant yield responses of maize, castor, groundnut, and mung bean to the applications of S, B, and Zn over farmer?s input treatment, and the yield responses were larger when these nutrients were added along with nitrogen (N) and P.

We tested a stratified, random sampling methodology to ascertain whether surface geology, microwatershed, position on the toposequence, and size of farm holding explained the differences in the fertility parameters of soils in the semi-arid tropical region of Karnataka State, India. Descriptive statistics revealed that out of 119 farmer fields sampled, many were deficient in the following nutrients: 50% in available phosphorous (P), 78% in boron (B), 67% in zinc (Zn), and 72% in sulfur (S). Discriminant analysis indicated that fertility studies on a regional scale need to include good representation of soil heterogeneity based on parent material (surface geology), hydrological properties, and positions on toposequence but not the size of the farm holding. The proposed stratified random sampling technique enabled representation of the heterogeneity in the whole population even with a small sample set size},

abstract = {On-farm trials were conducted in the central Karnataka of India, over 3 years, with the objectives of quantifying the effects of applying balanced nutrition to rain fed maize with regard to yield response, plant nutrition, profitability and rain water use efficiency under multi-nutrient deficient conditions. Maize grain yield was significantly increased by the soil application of Farmers? Inputs (FI) plus additional quantities of nitrogen and phosphorus (NP), FI+sulfur, boron and zinc (SBZn) and FI+NP+SBZn treatments compared to maize receiving no fertilizer inputs or FI. Optimizing limiting soil nutrients significantly (pensuremath<0.05) enhanced grain productivity by an average of 67.1% and stover yields by 76.6% under farm situations. Also the treatment NP+SBZn over the FI treatment significantly increased the uptake of N, P, K, S and Zn in the grain and above-ground maize parts. Use of SBZn, along with the FI?s enhanced partial factor productivity and agronomic efficiency by 202 and 96.8%, respectively. However, the benefit: cost ratio (2.9: 1) of SBZn treatment was not encouraging and it was most lucrative (6.4: 1) in FI+NP treatment. Maize fertilized with balanced nutrition (FI+NP+SBZn) showed greater rain water use efficiency (almost increased by 50%), over the farmer?s practice of fertilization. Integrated application of additional quantities of NP and correcting SBZn deficiencies in rain fed maize are critical for not only to enhance the productivity and profitability but also to maintain sustainable soil resource base.},

abstract = {Poverty, food insecurity, and malnutrition are pervasive in the serm-arid trOpICS (SAT) of South Asia, including India. I n rural areas, most of the poor make their livelihoods on the use of natural resources, which are degraded and inefficiently used. This is because of the inadequate traditional management practIces of managing agriculture as well as the fact that resulting crop yields are much below the expected potential yields. ICRlSAT in the early 1970s initiated research on watersheds for integrated use of land, water, and crop management technologies for increasmg crop production through efficient use of natural resources, especially ramfal! that is highly variable in the SAT and is the main cause of year-to-year variation in crop production ill India. Improved watershed management on Vertisols more than doubled crop productivity, and rainfall-use efficiency increased from 35% to 70% when compared wlth traditional technology. After many years of implementmg and evaluating these improved technologies in on-farm situations, many lessons were learned and they formed part of the mtegrated watershed management model currently being pursued by ICRlSAT in conununity watersheds in rural settings. This watershed model is more holistic and puts rural communities and theIr collective actions at center stage for implementing improved watershed technologies with technical backstopping and convergence by consortium partners. We describe here the achievements made in enhancing crop productivity and rainfall-use efficiency by implementing improved technologies in onfarm community watersheds in India.},

The experiences of the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in its research for development (R4D) projects provided substantive insights for the inclusion and empowerment of women in both the physical and social environment. Lessons learned for bringing in women's perspectives into projects include the importance of tangible economic benefits and users' perspectives in the management of local economies and social networks. These lessons led to women making a difference in the areas of village and organizational leadership, livelihood management and knowledge management, which are critical in addressing climate change impacts. Designing interventions for women requires an active process of social construction and negotiation, and that interventions should not be viewed as a package with simple and linear and systematic patterns.},

To learn from the past research, a review is made of literature on the impact of natural resource management practices on soil and water quality in the semi-arid tropical regions of India. The results from long-term on station field experiments show that an integrated use of soil and water conservation practices with balanced plant nutrition can not only sustain increased productivity but also maintain soil quality at the watershed or catchment level. Natural resource management practices that conserve soil and water also help to maintain surface and groundwater quality. The changes in soil and water quality, as impacted by natural resource management practices, need to be monitored and assessed on a continuing basis as the outcome of such research offers valuable opportunity for the implementation of corrective management practices, as and when needed.},

abstract = {Rainfed agriculture plays and will continue to play a dominant role in providing food and livelihoods for an increasing world population. We describe the world?s semi-arid and dry sub-humid savannah and steppe regions as global hotspots, in terms of water related constraints to food production, high prevalence of malnourishment and poverty, and rapidly increasing food demands. We argue that major water investments in agriculture are required. In these regions yield gaps are large, not due to lack of water per se, but rather due to inefficient management of water, soils, and crops. An assessment of management options indicates that knowledge exists regarding technologies,management systems, and planning methods. A key strategy is to minimise risk for dry spell induced crop failures, which requires an emphasis on water harvesting systems for supplemental irrigation. Large-scale adoption of water harvesting systems will require a paradigm shift in Integrated Water Resource Management (IWRM), in which rainfall is regarded as the entry point for the governance of freshwater, thus incorporating green water resources (sustaining rainfed agriculture and terrestrial ecosystems) and blue water resources (local runoff). The divide between rainfed and irrigated agriculture needs to be reconsidered in favor of a governance, investment, and management paradigm, which considers all water options in agricultural systems. A new focus is needed on the meso-catchment scale, as opposed to the current focus of IWRM on the basin level and the primary focus of agricultural improvements on the farmer?s field. We argue that the catchment scale offers the best opportunities for water investments to build resilience in smallscale agricultural systems and to address trade-offs between water for food and other ecosystem functions and services.},

The farmyard manure (FYM) itself contains reasonable amounts of nutrients which become available to plants upon decomposition besides enhancing availability of native as well as applied nutrients. The studies on the effect of B and FYM application on chemical composition of vegetables in general, and cauliflower in particular, are scanty. Therefore, greenhouse studies were conducted to investigate the effect of B and FYM on nutrient contents in cauliflower on two B-deficient soils collected from two varied agro-climatic conditions in North-West Himalayas of Himachal Pradesh.},

abstract = {Under the National Agricultural Innovation Project (NAIP) , three tribal-dominated districts (Adilabad, Khammam and Nalgonda) in Andhra Pradesh were selected to study the role of Site Specific Nutrient Management (SSNM) and balanced nutrition to enhancing income and livelihood security. By adopting a toposequence approach, 720 surface soil samples were collected from 39 villages with the participation of farmers. The soil sampling was based on stratified random sampling. Generally, it is believed that soils in the tribal region are rich in organic carbon and high in soil fertility because of relatively low intensity cropping. Contrary to this belief, the results of soil analyses showed that most of the soils are low to medium in organic carbon, low in available N and P, and low to high in available K. Among the secondary and micronutrients, S, B and Zn are the emerging nutritional constraints. By adopting SSNMand balanced nutrition approach, increase in yield ranged from 13 to 53% in cotton, 15 to 58% in chickpea, 18 to 44% in groundnut, 33 to 47% in green gram; and in vegetable crops, the increase in yield varied from 25 to 54% in tomato and 7-10% in Bhindi (Ladies fmger) over the farmer's practice (FP). Net income and return per Re investment also increased by balanced nutrition. In cotton, net income obtained ranged between Rs. 30783 and 55533 ha-1 in Adilabad, Rs. 15,030 and 70,533 ha-1 in Khammam under balanced nutrient management. In other crops, the net return was Rs. 5564-14214 ha-! in chickpea, .

The vulnerability of tanners to anticipated changes in patterns of supplies of natural resources particularly water shortage due to climate change requires optimum utiiization of water resources. In soil sample analysis from farmers fields in the semi arid regions of Rajasthan, available sulphur, boron and zinc varied across farmers fields from 1.9 to 274, 0.08 to 2.46 and 0.06 to 28,6 mg kg-1. The findings surprised with widespread deficiencies of sulphur, boron and zinc in addition to nitrogen and phosphorus. Farmer participatory experiments were conducted in the semi arid regions of Rajasthan on inclusion o f deficient secondary and micronutrients in the fertilizer recommendations for crop production along with improved cultivars. The integrated approach of soil and crop management recorded best yields by Way of improved water use efficiency in maize (2.42 times), pearl millet (2.51 times), and soybean (1,83 times).},
