RÉSUMÉ
Agriculture production in the Bundelkhand region is highly vulnerable to the climate change. To examine the perception, awareness, extent of knowledge on climate change and its impact on agriculture production with coping strategies, a research study was conducted with randomly selected, 70 sample farmers household from two villages of Datia district. More than 80 per cent farmer feels that climate change is serious issue, and it affects water availability and crop production. 77 percent respondents from watershed area expressed their view, that climate change reduced crop yield followed by the reduction in milk yield, disease and pest incidence, rainfall reduction and environment effect. Results shows that respondents of Jigna village (under watershed area) are reported to be more aware about impact of climate change (temp., rainfall, wind velocity) as compared to Dalipura village. Farmers from both villages were reported deforestation, intensified industrialize and air pollution as reason for consequence of climate change. Intensify research efforts and Enlightenment campaign as efforts to overcome climate change are reported by majority of respondents. Changes in existing cropping pattern and soil-water conservation measures suggested as coping-strategies for climate change.

To standardize the sieve size for seed grading in dhaincha during Kharif, 2019–20 and 2020–21, an experiment was carried out. The native dhaincha species was processed using slotted perforated metal sieves with CRD design ranging S1 - 1.4 mm (S), S2- 1.6 mm (S), S3- 1.8 mm (S), S4 - 2.0 mm (S), and S5- 2.2 mm (S). The study realized that 2.0 mm and 2.2 mm sieves recorded highest seed quality standards and yielded larger-sized seeds. the results revealed that the seed recovery per cent in the 1.4 mm screen was maximum, whereas, the seed quality, nevertheless was better when seeds were graded using 2.0 mm and 2.2 mm sieves. From the combined average data of the two years, the highest quality seeds were retrieved by grading the seeds using 2.0 mm screen with good seed recovery per cent viz., SR (92.99%), PP (98.46%), PLS (90.37%), TW (26.16 g), SG (81.63 %), TSL (25.2 cm), SDW (14.4 mg), SVI-I (2103) and SVI-II (1174). Hence, the 2.0 mm screen can be used to obtained highest quality seeds with economical seed recovery.

Pearl millet is an important millet crop, as it is a powerhouse of nutrition with capability to grow at harsh climatic conditions. It is able to overcome sudden climate changes and other natural disasters which can create food security problem by raising the price of foods there by reduce the availability of food materials. Pearl millet can be an alternative nutritious crop for the poor men which provide enough nutrition for active and healthy life. It is cheap source of nutrition when compared to other major cereal crops. While having its nutrition and health benefits, utilization of this crop is restricted due to lack of knowledge and poor keeping quality.Different breeding strategies like biofortification breeding, making of synthetic and composites, hybridization techniques by using A,B,R lines, Genomics, Speed breeding are frequently utilized in worldwide. Different improved lines with enhanced zinc and iron content may be used under hybridization programme to overcome the problem of low zinc and iron varieties. Therefore, the aim of this review is to provide the information about nutritional profile, health benefits, biofortification process, current breeding approaches and future prospects.
RÉSUMÉ
The water requirement for any cropping system is important consideration for designing and managing irrigation systems. Water requirement of crops varies substantially over the growing season mainly due to variation in crop cover and climatic conditions. For estimating crop water requirement of tomato crop, we have taken field experiment in weighing lysimeter for three seasons rabi - (7th September 2021 to 5th January 2022); Summer - (15th January 2022 to 15th May 2022) and Kharif - (6th June 2022 to 4th October 2022). The crop water requirement helps us to develop the crop coefficients for various growth stages (initial, development, mid and late season) for particular climatic conditions. Further, with exact crop coefficients derived from weighing type lysimeter will be helpful for determining water requirement. The results showed that the crop evapotranspiration (ETc) for initial, development, mid-season and late-season being 22.76, 110.71, 173.47 and 68.71 mm, respectively. With respect to crop coefficient (Kc), it is estimated to be 0.38, 0.64, 1.12 and 0.66 for initial, development, mid-season and late season stages, respectively during rabi season. The crop evapotranspiration (ETc) for initial, development, mid-season and late-season being 26.53, 164.76, 235.56 and 121.51 mm, respectively. With respect to crop coefficient (Kc), it is estimated to be 0.56, 0.87, 1.22 and 0.78 for initial, development, mid-season and late season stages, respectively during summer season. The crop evapotranspiration (ETc) for initial, development, mid-season and late-season being 32.31, 131.38, 173.51 and 60.13 mm, respectively. With respect to Kc, it is estimated to be 0.36, 0.77, 1.13 and 0.74 for initial, development, mid-season and late season stages respectively during kharif season. The measured Kc values were significantly different from the FAO-56 reported values. Therefore, local calibration of crop coefficients is an essential for efficient irrigation water management and precise water applications.
