“…The annual average rainfall of district is 633 mm which is not uniformly distributed over the district and predominant soil types were red and deep black soils. Vijayapura district is located in the northern part of Karnataka, low annual and unimodal rainfall with medium to deep black soils with diversified system of cropping (Dupdal et al, 2022) and lies between 15 o 50' and 17 o 28' North latitude and 74 o 54' and 76 o 28' East longitudes. The average rainfall of district is 594 mm with more than 50 percent of rainfall received during rabi season.…”

This study ascertained the impact of water harvesting structures-farm ponds constructed under Krishi Bhagya Scheme in Northern dry zone of Karnataka during 2019 to 2021. Farmers with and without farm ponds were selected through multi-stage random sampling technique with a total sample size of 320 farmers for data collection. The impact of farm ponds on cropping pattern and crop productivity was visible due to supplementary life saving irrigation. The change in income due to farm ponds ranged from 13 to 97 per cent and net returns realized by farmers with ponds was higher than the farmers without ponds due to increased crop yield. The employment generation per farm increased for beneficiary farmers as compared to control. However, problems of sedimentation, poor design of farm ponds (absence of silt trap and proper inlet and outlet), poor site selection and lack of awareness were the major constraints experienced by farmers for long term sustainability of farm ponds.

“…Adoption of micro-level agro-advisory services helped farmers in their farm planning, better crop management, efficient utilization of existing farm resources while improving the productivity and farm incomes (Dupdal et al, 2021). The farmers sustained crop yields by adopting climate resilient indigenous and modern scientific technologies like manipulating sowing dates, mixed farming, crop diversification, alternate cropping systems and drought tolerant varieties (Dupdal et al, 2022). It is suggested that ways and means of estimating TOT for the whole farm (farming systems approach) have to be developed to measure the profitability of agriculture at farm household level.…”

This study estimated the Terms of Trade (TOT) between the input and output prices for pearl millet, wheat, paddy and gram crops cultivated in Jaipur, Sri Ganganagar, Hanumangarh and Ajmer districts respectively in Rajasthan state for the period 1996-97 to 2018-19. It was found that the Compounded Annual Growth Rate (CAGR) of Procurement Price Index (PPI) and Farm Harvest Price Index (FHPI) have increased consistently for all crops with a CAGR ranging from 5-8 per cent p.a. The CAGR of Composite Input Price Index (CIPI) was always higher (ranging from 6-8% p.a.) than the PPI and FHPI indicating that the input prices have increased at a much higher rate than the output prices during the study period. Analysis revealed that TOT (ratio of PPI to CIPI and ratio of FHPI to CIPI) for all crops for most of the years was unfavourable (<100) as evident from negative CAGR (ranging from -0.15 to -2.40% p.a.). The selection of the base year in which output prices are around 150% (i.e. 1.5 times the cost of cultivation) of the composite input prices for estimating TOT is recommended. The study further explored as to why farmers cultivated these crops despite declining and negative TOT.

IntroductionRedgram (Cajanus cajan L. Mill sp.), a leguminous crop commonly grown in tropical and subtropical climates, is highly valued for its high protein content (21%), which contributes significantly to food and nutritional security. However, its production faces challenges primarily due to terminal dryness experienced during critical growth stages because of changing rainfall patterns. To overcome this, adaptive techniques become imperative as the productivity of this crop is intricately linked to environmental factors and the crop’s growth cycle.MethodsHence, the field experiment was conducted at the National Pulses Research Centre, Vamban, Pudukkottai, Tamil Nadu, in South India under rainfed condition, during the kharif (monsoon) seasons of 2017–18 and 2018–19. The primary objectives were to determine the optimal sowing time and identify suitable redgram cultivars, especially in the context of the late onset of the monsoon in Tamil Nadu, a common issue under changing climate conditions. The experiments tested six different sowing dates with three redgram cultivars.Results and discussionThe findings highlighted the substantial influence of different redgram cultivars and sowing times on the crop’s growth characteristics and yield. Among the six sowing dates tested, planting in later half of June (S6) resulted in notably higher plant height (201 cm), a greater number of pods per plant (287), a seed yield of 1,112 kg ha−1, and a benefit-cost ratio of 2.61 Notably, this sowing period (S6) demonstrated comparable performance with the treatment of redgram sowing in the latter part of September (S4). CO 6 (V1) is the most productive of the three redgram cultivars, with the highest mean pant height (200 cm), number of pods per plant (237), grain yield (1,017 kg ha−1), and benefit cost ratio (2.38). Extended phenological phases along with extra days to reach phenological stages could account for the increased yield in comparison to the other cultivars. Among the two short-duration cultivars, VBN (Rg) 3 (V3) had a significantly higher mean grain yield of 958 kg ha−1 with the benefit-cost ratio of 2.24. Even though CO 6 (V1) obtained a higher yield due to its long duration nature, it matured in 187 days whereas VBN (Rg) 3 (V3) matured within 129 days. Consequently, the short-duration redgram cultivars emerge as highly suitable choices for integrating into crop sequences, thereby augmenting farm cropping intensity.
