The water resources in the state of Rajasthan are in a crucial stage due to uneven and erratic distribution of rainfall. Due to rapid urbanization, industrialization and increasing population, the pressure on agriculture
specifically using groundwater sources is increasing and causes a depletion of surface and ground water availability. Hence, there is an urgent need to explore the possible ways to meet out the irrigation needs in water deficit area for efficient utilization of irrigation water. In the water deficit area, micro-irrigation (drip irrigation and sprinkler systems) has the potential to address problems like water scarcity for agriculture and horticultural crops. Micro irrigation systems realizing
the potential for reducing crop water requirement by increasing water use efficiency and address future water scarcity at the regional and national levels.

Field experiment was carried out at Instructional Dairy Farm, G B pant University of Agriculture & Technology, Pantnagar during winter season of 2017-18 to study the effect of cultivars and phosphorus level on yield and quality of berseem (Trifolium alexandrinum L.). Berseem variety BB-2 gave significantly higher green and dry fodder yield and closely followed by varieties Mescavi and PC-82. The crude protein content was
also recorded higher in BB-2 but NDF and ADF were lower than other berseem varieties. The phosphous application @ 100kg/ha produced significantly higher green and dry fodder yield that was 4.8% and 4.7%
greater than 80 kg P levels, respectively. The leaf:stem ratio, crude protein content, NDF and ADF were not influenced significantly by phosphorus levels. Therefore it can be concluded that ‘BB-2’ can be grown at application of 100kg P/ha for higher productivity in Tarai region of Uttarakhand.

A field experiment was carried out to study the effect of different spacing and levels of phosphorus on growth and yield of kabuli chickpea (Ciceraeritinium Var. kabulium L) variety KAK-2 at the Crop Research Farm of SHUATS, Allahabad, during winter season in 2018. The results revealed that different Spacing (20cm, 30cm, and 40cm) and phosphorus levels (25 kg ha-1, 40 kg ha-1, 55 kg ha-1, and 70 kg ha-1) significantly affected plant height, no. of root nodules and number of
pods per plant. The maximum plant height (28.22 cm) was recorded from treatment no. 8 (55 kg P ha-1 and 30 cm spacing) at 60 DAS. Similarly, higher number of root nodules (23.62) per plant was recorded from the treatment no. 12 (40 cm spacing and 70 kg Phosphorus ha-1) at 60 DAS. The maximum number of pods per plant (24.33) was observed from the treatment no. 8 (55 kg P ha-1 and 30 cm spacing). Generally the results revealed that treatment no. 8 (55 kg P ha-1 and 30 cm spacing) gave better performance in approx all the parameters studied.

Field experiment was carried out at Instructional Dairy Farm, G B pant University of Agriculture and Technology, Pantnagar during winter season of 2016– 17 to study the effect of promising entries and nitrogen
levels on yield and quality of oat (Avena sativa L.). The experimental site was sandy loam with neutral soil pH and available nitrogen, phosphorus and potassium were 278.5, 27.7 and 232.8 kg/ha, respectively. The experiment consisted of 11 oat entries i.e. Kent, OL– 1766–1, OL–1802, UPO–10–3, OS–6, SKO–225, OL– 1769–1, OS–424, OS–432, JO–04–19 and OL–125 in main plot and 03 N levels i.e. 40, 80 and 120 kg/ha in sub plot was laid out in split plot design with three replications. The 50% flower, the plant height, number of tillers/m row length, green and dry fodder yield were affected significantly by oat entries (Table 2). The maximum and minimum days to 50% flowering were observed under
OS–6 and OL–1802, respectively. Significantly tallest plants were found under OS–432, while OS–424 gave the shortest plants. Entry JO–04–19 gave the highest green and dry fodder yield followed by OS 424. The
highest and the lowest CP were recorded in OL–1802 and OS 424 entries. The green and fodder yield, CP and NDF increased from 40 to 80kg N/ha, while ADF was recorded lowest at 120 kg N/ha.
