International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad T3-34P-1554 Productivity Enhancement of Lentil (Lens esculenta Moench) in Rainfed Agro-ecosystem in Koshi Region of Bihar K.M. Singh 1 *, Md. Nadeem Akhtar 1 and Amarendra Kumar 2 1 Krishi Vigyan Kendra, Agwanpur, Saharsa -852201, Bihar 2 ICAR-ATARI, Zone IV, Patna *kmsingh66@gmail.com Lentil (Lens esculenta Moench.) is an important rabi season pulse crop of Bihar. Farmers generally go for sole and paira cropping of lentils under low fertility and poorly managed soil in rainfed agro-ecosystem in the Koshi region resulting in poor yield of the crop. These areas are also vulnerable to drought and flood. The present investigation conducted as an On-Farm trial on farmer’s fields during 2019-20 & 2021-22 revealed that the technology of Improved variety (HUL 57) + Recommended Fertilizer (20:40.:20 kg N: P: K/ha) + Biofertilizer (Rhizobium and PSB@ 1 liter/ha) + Boron 1 kg ai/ha enhanced the productivity of lentil from the farmers level of 6.50 q/ha to the tune of 11.50 q/ha. This could be achieved with a better expression of yield contributing factors (branches/ plant, pod/plant, seed/pod, 1000-seed wt.) due to the balanced nutrition of plants. The economics of study also realized higher net return (Rs 38000/-) and B: C ratio (2.94) under the technology option of improved variety (HUL 57) + RDF+ Biofertilizer (Rhizobium culture, PSB) + Boron 1 kg ai/ha in comparison to farmer’s practice. The application of recommended fertilizer along with biofertilizer (Rhizobium & PSB) has also contributed to improvement in soil fertility parameters.

Punithavathi Indian Council of Agricultural Research Hans Roever KVK, Perambalur District, Tamil Nadu Banana is an important fruit crop in Kurumbalur village of Perambalur district, Tamil Nadu. The productivity is low due to occurrence of drought during critical period of growth stage of banana. Also, major part of the village is affected with saline irrigation water. Thus affects the soil properties and inhibit the uptake of nutrients and leads to reduction in yield. Therefore, efforts have been made to demonstrate improved drought tolerant banana variety ‘Kavery saba’ to increase productivity which is also suitable for saline, sodic and marginal soils through front line demonstration. The variety Kaveri saba was released by NRC Banana, Trichy during the year 2019. The present study was carried out by Krishi Vigyan Kendra, Perambalur, Tamil Nadu to assess the impact of popularization of Banana variety Kaveri saba.

International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad that, the Banana variety Kaveri saba was performed well in Kurumbalur hamlets of Perambalur district also given the high yield under less irrigated condition during rabi season (2020-22). An average yield of 468.56 q ha -1 was recorded in front line demonstration and in farmer practices it was just 392.23 q ha -1 . Thus, the average technology gap, extension gap and technology index of 121.44, 76.33 and 20.50 percent were observed between demonstration and farmer practices. The average yield of banana increased by 20.58 percent over farmers' practices. Moreover, farmers inferred that the fruits have high market preference and fetching premium price owing to its good keeping quality with green life of 7-8 days.

Dry regions of West Africa as well as India are considered as centres of origin of cluster bean though diverse opinion on exact origin of cluster bean is still prevails. It is characterized as a short-day erect or bushy annual plant (Purseglove, 1981). It is a drought tolerant, warm season legume crop with deep and well-developed root system, cultivated mainly as rainfed crop in arid and semi-arid regions during rainy (kharif) season for vegetable, galactomannan gum, forage and green manure. Cluster bean is mainly cultivated for food, feed and fodder (Reddy et al., 2017). North Eastern part of Karnataka experiences frequent and intermittent droughts coupled with high temperature. The farmers are following the traditional cropping system of Rabi sorghum-sunflower production system. The market price of Rabi sorghum is very low and that of sunflower is very much fluctuating and often gets infected with powdery mildew. The variation in market price results in loss to the farmers and even they are unable to meet out the cost of cultivation. Rabi sorghum is the main food crop of the Northern Karnataka. Hence farmers are growing rabi sorghum for food requirement and fodder to their livestock. Apart from growing Rabi sorghum, there is a scope for introduction of cluster bean (gum type) so that the farmers can get an additional income apart from food grains. Keeping the above in mind the present investigation was taken up to evaluate and identify the suitable genotype and to standardize the suitable planting geometry.
