SUMMARY

Principal factor analysis was done in Sesbania(using 57 genotypes and 17 variables) which identified five principal factors explaining 70.97% variability altogether. The principal factor analysis without rotation failed to provide clear picture, hence varimax rotation was applied which resulted into clear cut loading of almost similar type of variables on a common principal factor permitting to designate them as grain yield factor, green manuring factor, growth rate factor, etc., according to the type of variables it is loaded with. Genotypes LJ 32, Ses H 3, LJ 37, Ses H 22 and Ses H 33  were found to be better performers with regard to grain yield and its components when all the principal factors were considered simultaneously. These genotypes can further be utilized in breeding programmes for improving grain yield. Further, hierarchical cluster analysis (UPGMA with city block distances) was carried out to classify these 57 Sesbania genotypes on the basis of seventeen grain yield and green manuring related variables which resulted into formation of seven clusters having one to fourteen genotypes. The results of hierarchical cluster analysis and principal factor analysis confirmed the findings of each other.

Key words: Cluster analysis, Sesbania, germplasm and principal factor analysis.

SUMMARY

A field experiment was conducted to study the effect of method of nitrogen application on yield and quality of barley under furrow irrigated raised bed system (FIRBS). Results indicated that sowing under FIRBS 90 cm (3 rows) recorded significantly higher grain and straw yields as compared to FRIBS 90 cm (2 rows) and FRIBS 75 cm (2 rows). Application of nitrogen (N) on top of bed also brought significant improvement on grain and straw yield over N application by broadcasting method. Application of N on top of bed increased the protein content, husk content and decreased in the malt content and hot water extract over N application by broadcasting, however N application before or after irrigation either on top of bed or broadcast did not reflect any significant variation in term of yield and quality parameters.

SUMMARY

A field experiment was conducted to identify suitable crops for Jatropha based intercropping system during winter season of 2005-06 and 2006-07 at Department of Forestry Farm, CCS HAU, Hisar. The production potential of  mustard (Brassica juncea) cv. RH-30, Eruca sativa cv. T-27, chickpea (Cicer arietinum) cv. HC-5 and barley (Hordeum vulgare) cv. BH-393 were evaluated under 5m x 3m spacing of Jatropha. Jatropha plantation had  significant effect on the growth and yield of test crops during both the year of experimentation. However, the growth, yield and yield attributes of all the test crops were reduced more in second year as compared to first year of experimentation. Two year old Jatropha produced negligible seed yield both during 2005-06 and 2006-07 due to frost injury in 2005-06 and excessive vegetative growth during 2006-07. Therefore, susceptibility of Jatropha to frost, requirement of irrigation for flowering and fruiting and poor seed yield has rendered it unsuitable for north India.

SUMMARY

The present study was carried out in the Department of Soil Science, CCS HAU, Hisar during kharif season in screen house. The experiments were conducted on a sandy soil having initial pH (1:2) 8.21 and ESP 7.88. Soil of different ESP (15, 30 and 45) was prepared. Observed ESP was 7.88, 13.86, 31.15 and 43.79, respectively. The first experiment was conducted in screen house to study the effect of different ESP levels (control, 15, 30 and 45) on pearl millet (HC-20) with fixed 80 kgN/ha dose. In second experiment different Nitrogen levels, 0, 40, 80, 120 kgN/ha on pearl millet at an ESP of 45 were studied. The results on the studies on different ESP levels, revealed that the dry matter yield, plant height, protein content and uptake of nutrients (N, P, K, Ca, Mg & S) decreased with increasing ESP levels. The uptake of micronutrients (Zn, Cu, Mn, & Fe) in pearl millet decreased with increasing ESP levels. However, the studies on different levels on different levels of Nitrogen at 45 ESP, revealed that the dry matter yield, plant height, protein content and uptake of nutrients, N, P, K, Ca, Mg, Na, S, Zn, Cu, Mn, & Fe by pearl millet increased with increasing Nitrogen levels

SUMMARY

                A field experiment was conducted at Research farm, CCS HAU, Hisar, laid out in split-plot design with treatments comprising of four nitrogen (0, 40, 80 and 120 kg N/ha) and two bio-fertilizer (no inoculation and inoculation with Azotobacter chrococcum) levels in main plots and five levels of organic manures (control, FYM @ 5 t/ha, FYM @ 10 t/ha, vermicompost @ 5 t/ha and vermicompost @ 10 t/ha) in sub-plots, replicated thrice. Application of nitrogen levels significantly improved green fodder yields at fodder harvest (75 DAS), yield attributes, grain and straw yields and net returns up to 80 kg N/ha. Inoculation of oats seed with Azotobacter improved significantly the green fodder yield, yield attributes, grain and straw yields and economic returns of oats during both the years. Among five levels of organic manures, application of vermicompost @ 10 t/ha resulted in maximum green fodder yield, yield attributes, grain and straw yields and economic return which were statistically at par recorded in FYM @ 10 t/ha. Azotobacter inoculation had pronounced effect under no nitrogen or at lower levels of nitrogen than higher levels of nitrogen during both the years of experimentation.

 SUMMARY

Fodder Yield of front line demonstration trials and potential yield of the respective variety and year were compared to estimate the fodder yield gap which were further categorized into technology and extension gaps. Technology gaps (3154 kg/ha) was highest in case of RHB 121 at village Singwara in 2008 and lowest (840 kg/ha) of RHB 121 at village Aluda, Reta in the year 2011. Average technology gap were 2272 kg/ha. Extension gap was highest in variety RHB 121 (880) at village Aluda, Reta in year 2011, and lowest (190) at village Malwas in variety RHB 121 in year 2012.  The average extension gap was 443 kg/ha. Technology index was the highest 110.82 per cent at village Singwara in the year 2008, and lowest 16.28 per cent at village Aluda, Reta in 2011 with the variety RHB 121. The average technology index was found 69.30 per cent. The highest pearl millet fodder yield of FLD were found 5290 kg/ha and lowest yield were found 2846 kg/ha.  Average fodder yield of front line demonstration were found 3854 kg/ha and in local check/ farmers practice it was 3411 kg/ha.  The study indicated that average per cent increase in fodder yield was 13.16 (443 kg/ha). Average per cent increase of gross return were found 15.98 per cent and average net return were found 25.44 per cent which shows front line demonstrations can be increasing the living standard of farming community of Dausa District. Across the years front line demonstrations were found higher fodder productivity ranging from 8.75 to 20.56 per cent and higher B: C ratio from 1.67 to 4.34. Front line demonstrations shows in respect of per cent increase of yield and B:C ratio is sufficient for increasing production of pearl millet and increasing living standard of farmers community of Dausa district. The study reveals that overall per cent increase in net returns was 25.44 (Rs 1920/ha). It assumes that if farmers of Dausa district adopt the demonstrated technology in current pearl millet area (125000 ha) can earn additional benefit in terms of net return over farmers practice Rs. 24 crores per year improving their socioeconomic status of the farmers
