The field experiment was conducted at Bikaner (Rajasthan) during kharif season of 2010 to find out the proper time of sowing and optimize the nitrogen requirement of sewan grass (Lasiurus sindicus) in hot arid region. Results indicated that first date of sowing i.e. first week of July (4th) resulted significantly higher fresh forage yield (172.2 q/ha), dry matter (59.9 q/ha) yields, CP content (8.71%), CP yield (525.3 kg/ha), net returns (Rs.14,278/ha) and B:C ratio (2.47) over other dates of sowing viz., first week of August and first week of September. While, in case of nitrogen, although forage productivity and quality were improved up to the highest dose i.e. 60 kg N/ha and recorded fresh forage yield (98.6 q/ha), dry matter yield (35.4 q/ha), CP content (8.95%) and CP yield (320.8 kg/ha) but significantly increased only upto 40 kg N/ha and maximum values of net returns (Rs. 4,737.0/ha) and B:C ratio (1.51) were also recorded with 40 kg N/ha. Interaction effect of date of sowing and nitrogen on forage and CP yield was significant and data showed that values recorded with first date of sowing under 40 and 60 kg N/ha were at par but significantly higher over rest of the treatment combinations. Maximum values of energy ratio and energy productivity were recorded with the sowing in first week of July (12.7 and 702.8 g/MJ) and nitrogen applied @ 20 kg N/ha (7.3 and 402.8 g/MJ). Overall, it was concluded that for getting higher and economic forage yields, sewan grass should be sown in first week of July and fertilized with 40 kg N/ha in hot arid region of Rajasthan.

Seed yield is a complex character governed by several contributing characters. Hence, variability and the extent of variation along with heritability were assessed for seed yield and its seven attributing traits in CMS based rabi sorghum hybrids. The study indicated moderate heritability coupled with low to high genetic advance for various traits. Character association was studied to assess the relationship among yield and its component characters for enhancing the usefulness of the selection criterion to be followed. The study revealed that most of the yield attributing traits viz., days to 50% flowering, days to maturity, panicle length and test weight exhibited positive significant correlation with seed yield. Path analysis revealed that panicle length, number of leaves per plant, test weight and fodder yield exhibited positive direct effects on seed yield at phenotypic level.

A field experiment was conducted during rabi 2011-2012 at Research Farm, CCS Haryana Agricultural University, Hisar, Haryana (India) in a semi-arid climate to study the Water productivity of barley cultivars in relation to row spacing and moisture regimes planted on raised beds. The experiment was laid out in split plot design with three replications keeping three cultivars viz., BH 393, BH 902 and BH 885 and two rows spacing viz, 2 rows per bed and 3 rows per bed (70 cm wide with 40 cm top and 30 cm furrow) in main plots and three moisture regimes (irrigation at IW/CPE 0.3, 0.4 & 0.5) in sub plots. The results revealed that maximum soil moisture depletion, ground water contribution and total water use were recorded in BH 902, followed by BH 393 and BH 885. Productivity of irrigation and total water use was highest under BH 902, followed by BH 393 and BH 885. Among two row spacing, Soil moisture depletion, ground water contribution and total water use were recorded higher in 3 rows per bed than 2 rows per bed. Comparatively higher irrigation and total water productivity were achieved in barley planted on raised beds with 3 rows per bed than 2 rows per bed. Among three moisture regimes, the soil moisture depletion and ground water contribution at 60 DAS to maturity, decreased with increase in moisture regime from irrigation at IW/CPE 0.3, to irrigation at IW/CPE 0.4 or 0.5. But total water use was increased with increase in moisture regime, being similar with irrigation at IW/CPE 0.4 and 0.5. The irrigation water productivity decreased with increasing moisture regime. However, productivity of total water use increased with increase in moisture regimes.

In the field study conducted at Research Farm of Agro-forestry, Department in CCS Haryana Agricultural university, Hisar and sowing of Barseem (Trifolium alexendrinum L.) var. Muscavi was done on 2nd week of October in Two & half year old eucalypts planted at 6m×2m spacing at the same time the crop was also shown in the adjacent field devoid of trees (Control). The data recorded on plant height, stem diameter, yield and economics revealed that no doubt all these parameters are high in case of sole crops of berseem but if we consider the need of the farmer that requires regular income from his piece of land then it seems practical that berseem as fodder can be grown successfully in standing eucalypts with additional income of Rs.3081 per hectare.

The experiment was carried out at the Student Farm of CCS HAU, Hisar for two consecutive kharif seasons of 2011 and 2012. The field was laid out in a split plot design following the block randomization system with three replications. Four varieties (HC 541, HC 308, HC 171 and HJ 513) and five nitrogen levels (0, 40, 60, 80 and 100 kg N ha-1) were taken in the main plots and subplots, respectively. Data collected revealed that grain and straw yields were significantly affected by both variety and nitrogen application. HJ 541 gave the highest grain and straw yields (1973 kg ha-1 and 18086 kg ha-1) with nitrogen application of 100 kg N ha-1, respectively. Nitrogen application enhanced N content and uptake in grain, but a non significant effect was recorded in straw by varieties. A non significant response was noticed with N application on P content in grain while P content in straw was significant. Nitrogen levels significantly affected K content in both grain and straw. Total uptake of NPK was enhanced by nitrogen application at all levels while control recorded the lowest total NPK uptake.

In order to select best suited dual purpose barley variety, to work out optimum fertilizer levels and seed rate, a field experiment was conducted during rabi 2009-10. The treatment consisted combinations of two dual purpose varieties (RD 2552 and RD 2035), three seed rate (100, 125 and 150 kg/ ha) and three fertilizer levels (100 per cent RDF: 60 + 20 kg N + P2O5/ha, 125 per cent RDF and 150 per cent RDF). Green fodder yield and growth character of dual purpose barley variety RD 2552 before and after green fodder cutting was significantly higher over RD 2035. The variety had higher grain and straw yield, accumulated maximum N and P in green fodder, grain and straw and total uptake compared to variety RD 2035. This manifested in additional net returns of Rs.4958 ha-1 over RD 2035 and increased B:C ratio from 1.4 to 1.7.
Application of 125 kg seed/ ha proved best and economically profitable over 100 kg seed/ha. The results revealed that application of 125 and 150 per cent RDF improved growth parameters, yield attributing parameters, grain, straw yield, N and P uptake over 100 per cent RDF. Protein content increased and crude fibre content of green fodder decreased with increasing fertility levels. However, TDN remains stable under varying fertility levels. With highest net returns and B:C ratio application of 125 per cent RDF proved most economically benificial.
