Field experiments were conducted during winter seasons of 2010-11 and 2011-12 at Bikaner (Rajasthan) to study the effect of bioregulators viz., TGA and N-acetyl cystein under different drip irrigation levels on yield, yield attributes, water use and water use efficiency of fenugreek. The highest plant height (69 cm) and yield attributes viz., branches plant -1 (7.6), pods plant -1 (46.3), pod length (13.5 cm), seed pod -1 (16) and test weight (12.7 g) were recorded with 100% ETc + TGA (200 ppm). Further, 80% ETc + TGA (200 ppm), and 100% ETc + N-acetyl cystein (both 10 and 20 ppm) and 100% ETc + TGA (both 100 and 200 ppm) produced comparable plant height. However, 80% ETc + N-acetyl cystein (both 10 and 20 ppm), 80% ETc + TGA (both 100 and 200 ppm), 100% ETc + N-acetyl cystein (both 10 and 20 ppm), 100% ETc + TGA (100 ppm) and 100% ETc + TGA (200 ppm) recorded at par branches plant -1 , pods plant -1 , pod length and test weight of fenugreek. Highest seed and biological yield of fenugreek were recorded with 100% ETc + Nacetyl cystein (20 ppm), which was at par with 100% ETc + N-acetyl cystein (10 ppm) and 100% ETc + TGA (both 100 and 200 ppm). Maximum water use recorded at 100% ETc with or without bioregulators, whereas maximum water use efficiency was recorded with 60% ETc + N-acetyl cystein (20 ppm) followed by 60% ETc + N-acetyl cystein (10 ppm).

A field experiment was conducted during Rabi season, 2011-12 at Niche Area Excellence Farm, Bikaner to study the effect of crop geometry, drip irrigation and bio-regulator on growth, water use efficiency and yield of wheat (Triticum aestivum L.). The experiment was conducted in Randomized Block Design with three irrigation schedules viz., 60, 80 and 100 per cent ETc, two crop geometry levels viz., 22cm paired row spacing-4 rows (120 cm lateral spacing) and 22 cm normal spacing sowing (60 cm lateral spacing) and two levels of bioregulator viz., control (water spray) and thiourea (500 ppm) foliar spray twice at vegetative stage and flowering stage. The study indicated that there was increase in dry matter accumulation, plant height, grain yield and biological yield with increase in irrigation level from 60 per cent ETc to 100 per cent ETc. The study further indicated that dry matter accumulation and plant height was maximum in paired row as compared to normal planting whereas grain yield, biological yield and harvest index were maximum in normal planting as compared to paired row planting. The study indicated that dry matter accumulation significantly increase only 60 and 120 DAS and plant height at only 120 DAS with the thiourea (500 ppm) as compared to control. The study also indicated that the interaction effect of irrigation and geometry gave maximum grain yield, biological yield and WUE at 100 per cent ETc +60 cm drip line spacing, maximum harvest index at 60 per cent ETc + 60 cm drip line spacing whereas maximum WUE at 80 per cent ETc + 60 cm drip line spacing.

With a view to develop value added products, from aonla cultivar NA-7, syrup was prepared under different treatments. The prepared syrup was kept at ambient condition for storage study. The syrup remained acceptable upto 240 days at ambient condition. The syrup prepared from T-3 (35 per cent juice, 65 per cent TSS and 1.3 per cent acidity) recorded maximum organoleptic score than other recipe treatments. The biochemical composition in aonla syrup prepared from T-6 (50 per cent juice, 65 per cent TSS and 1.3 per cent acidity) had the maximum retained acidity, TSS, total sugar, reducing sugar than rest of the treatments and their increasing trend with advancement of storage period upto 240 days was recorded under ambient condition. On the other hand, the syrup prepared with T-6 (50 per cent juice, 65 per cent TSS and 1.3 per cent acidity) had maximum ascorbic acid, non-reducing sugar and organoleptic score and these traits showed decreasing trend with increasing storage period upto 240 days under ambient condition. The syrup prepared from T-3 (35 per cent juice, 65 per cent TSS and 1.3 per cent acidity) had the maximum benefit: Cost ratio, high sensory evaluation score and high nutritional quality.
