International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad T2a-16P-1077 Assessment of Different System of Rice Cultivation Technique for Combating Climatic Aberrations in Rainfed Medium Land Situation of Purulia District of West Bengal, India during kharif season S.K. Bhattacharya, B. Maity A. Chakraborty, M.K. Bhattacharjya, S. Thakur, P. Biswas and J. Gorain Krishi Vigyan Kendra Kalyan, Purulia, 723147, West Bengal, India kvkkalyanpurulia@gmail.com Rice is the staple food for 65% population of India which is increasing at a rate of 1.6% per year. Considering climatic aberrations like delayed onset of monsoon, intermittent drought and abnormally high temperature results in, not only transplanting of over-aged seedlings with low productivity, but also a major portion of rainfed Rice area remain fallow that brought down the overall area under rice cultivation during kharif season. Hence, there is a need to increase the productivity of rice to feed the burgeoning population under changing climatic situation. Field experiments were conducted to assess the suitability of System of Rice Intensification (SRI) and Direct seeding of pre-germinated paddy seeds using Paddy Drum Seeder with Farmers’ practices of transplanting rice variety MTU-7029 under rainfed medium land situation. The experiment was conducted in Jahajpur KVK instructional farm and Haramjanga (NICRA Village of KVK,), village of Purulia, West Bengal for the last three consecutive years. The results show SRI method and Direct seeding of pre-germinated paddy seeds using Paddy Drum Seeder. Both significantly out-yielded Farmer’s Practice of transplanting by 58.59% and 8.19% respectively. Moreover, the cost of weed management using cono weeder in SRI field and Direct Seeding was also reduced by 433.33% and 263.63% respectively when it is compared with Farmer’s Practice of rice cultivation. It has also been revealed that improved technologies like SRI and Direct seeding of pre-germinated paddy seeds resulted higher net income Rs. 28,300.00/ha with a B:C ratio of 1.87 and Rs. 10,220.00 with a B:C ratio 1.52 respectively as compared to Farmer’s Practice of rice cultivation of Rs. 5560.00 with a B:C ratio 1.36. Hence it may be concluded from the study that, SRI method of rice transplanting was found to be superior in producing more rice with less quantity of inputs such as water, seed, fertilizers and labour in view of combating climatic aberrations and stabilises the productivity with higher return. 276 | Page Climate resilient agriculture for risk mitigation

International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad T2a-17P-1120 Musk Melon Cultivation on Reservoir Basin: A Climate Smart and Profitable Farmer Practice in Arid Zone of Rajasthan Chandan Kumar*, Dheeraj Singh, M. K. Chaudhary and Arvind Singh ICAR-CAZRI, Krishi Vigyan Kendra, Pali (Rajasthan) India * chandan.kumar@icar.gov.in The harsh climatic condition and poor quality of soil and water in arid region of Rajasthan make crop production very challenging. Only hardy crop species with very less water requirement is grown in these areas mainly in kharif or rabi season where assured irrigation is available. Mean annual rainfall in the region varies from about 500 mm along the slope of the Aravallis in the east to 100 mm along the border with Pakistan in the west, more than 85% of which is received during the period of South West monsoon (June-September). The mean annual potential evapo-transpiration exceeds precipitation by a wide margin (1400- 2000 mm). Crop failure is a common feature either due to inadequacy of rainfall or due to shortage of soil moisture to meet the crop water requirements during different phenophases (Faroda et al. 2007). Besides this, the arid region has several biotic and abiotic limitations that are responsible for low productivity. Under these conditions local farmers utilized agro ecological knowledge to convert stress into opportunity with autonomous adaptation. One of such example is the cultivation of vegetable and fruits in the reservoir basin during winter and summer season in the arid zone of Rajasthan. The small and landless farmers residing in the catchment area of the reservoir realized the potential of the soil of reservoir basin and started to cultivate it for the production of vegetables on residual soil moisture. However, the crop yield and profitability is poor due to fast depletion of soil moisture in the absence of soil moisture conservation technologies. Gradually, several indigenous knowledge or practices has been evolved to enhance conservation of residual soil moisture, productivity and profitability of the cultivation in this basin. Such an indigenous technology includes production of musk melon in the reservoir basin of Hemawas Dam, Pali with indigenous knowledge that is similar to modern concept of conservation agriculture. Therefore, we evaluated and compared the socio-economic aspects of indigenously evolved conservation agricultural practices for the cultivation of musk melon in the reservoir basin of Hemawas dam with conventional practices of musk melon production.
