A field experiment on barley crop was conducted during Rabi 2006-07 at Punjab Agricultural University, Ludhiana. The treatments consisted of combination of three varieties (PL 172, PL 426 and RD 2552) and two row spacings (15 cm and 22.5 cm) in the main plots and two forage cutting stages (at 45 and 60 DAS) in the sub plots were laid out in split plot design with three replications. PL 172 variety gave significantly higher yields of dry fodder (19.4 q ha-1), crude protein (2.1 q ha-1), ether extract (10.52 q ha-1) and nitrogen free extract (10.31 q ha-1) than varieties PL 426 and RD 2552. Row spacing of 15 cm produced significantly higher yields of dry fodder (18.4 q ha-1), crude protein (1.9 q ha-1), ether extract (0.51 q ha-1), mineral matter (1.93 q ha-1) and nitrogen free extract (9.46 q ha-1) than the row spacing of 22.5 cm. The forage cut at 60 DAS produced significantly higher yields of dry fodder (24.2 q ha-1), crude protein (2.1 q ha-1), crude fibre (6.4 q ha-1), ether extract (0.62 q ha-1), mineral matter (2.31 q ha-1)and nitrogen free extract (0.62 q ha-1) than forage cut at 45 DAS. However, significantly higher crude protein content (13.3 %) and dry matter digestibility (76.06 %) was obtained in forage cut at 45 DAS.
Key words: Variation, time of cutting, row spacing, dry fodder, crude protein, dry matter digestibility and barley

The present investigation was carried out at Research Farm of Crop Physiology, Department of Agronomy, CCS Haryana Agricultural University, Hisar, India for two consecutive years from 2011 to 2012. The treatments comprised pearl millet genotypes HHB 67 (Improved), HHB 197, HHB 223 and HHB 234 and two environment viz. rainfed and irrigated. The experiment was laid down in factorial randomized block design with three replications. The results indicated that effective tillers (2.4), earhead length (22.8 cm), grain (31.18 q ha-1) and stover yield (84.68 q ha-1) significantly higher under irrigated condition than rain fed environment. Interaction effect of environment and genotypes showed higher number of effective tillers, earhead length, grain and stover yield in the genotype HHB 223 under irrigated condition compared to other genotypes. Under rainfed condition these were higher in the genotype HHB 234. Zinc and iron content in grain significantly higher under rainfed condition (58.03 ppm) than irrigated environment (53.31 ppm). Genotype HHB 67 ‘Improved’ recorded significantly higher Zinc (63.82 ppm) and iron content (45.84 ppm) in grain compared to all other genotypes.

A field experiment was conducted during kharif season of 2009 and 2010 at main Forage Research Area, CCS HAU, Hisar. The experiment was laid out in randomized block design with three replications and eight treatments (Table 1). The foliar application of 0.5% ZnSO4 at 35 and 45 DAS recorded maximum green fodder yield of 593.3 q/ha and 488.3 q/ha as well as dry matter yield of 171.6 and 141.6 q/ha during 2009 and 2010, respectively. The foliar application of ZnSO4 and FeSO4 with RDF does not improve the quality of fodder.

A series of balanced bipartite row-column designs (BBPRC- designs) in to sets of treatments with v1 = 4t+3 (test treatments) v2 = 2t+2 (Control treatments) with varying replication has been obtained by supplementing a set of v2 = 2t+2 treatments in blank positions of non orthogonal RC design of Agrawal (1966). Such designs find applications in agricultural and industrial experimentation where the investigator wishes to provide unequal replications to two set of treatments or wishes to estimate the two sets with different precaution and at the same time wants to estimate heterogeneity due to two sources. The variances for different types of comparison has also been worked out.
Key Words: BBPRC design. General efficiency balanced designs, non-orthogonal row-column designs.
