In the sub-tropical regions of India, the 1st to 3rd week of November is the optimum time for sowing wheat. A delay in sowing due to various factors causes a substantial yield reduction. Seeds of four wheat varieties (Sonak, UP 2338, Raj 3765 and PBW 343) were subjected to seed priming treatments involving water, salts, growth regulator and the sowing of sprouted seed under late-sown conditions during the winter seasons of 1998-99 and 1999-2000. The sowing of sprouted seeds resulted in significantly more rapid emergence of seedlings, accompanied by higher grain and straw yields. Seeds primed with IAA, KCl, water, ZnSO4 and Na2SO4 followed in this order. The lowest seedling emergence and grain yield were obtained for unprimed seeds. Seedling emergence was higher in the variety Sonak, while Raj 3765 and UP 2338 had higher leaf water, osmotic and turgor potentials during the 1998-99 season. The variety PBW 343 produced significantly higher grain and straw yields in the 1999-2000 season.

North West Himalaya Region of India faces serious shortage of green fodder up to 60 percent, particularly in winter months of November to March. Possibility of augmenting green fodder availability from cultivated lands, which is very limited (10% of geographical area) is explored by cultivation of dual purpose wheat, providing green fodder a part from grain production. Influence of wheat variation and their cutting schedule on fodder and grain yield were studied. Selected wheat varieties included VL Gehun 829, VL Gehun 616 and advance lines of VL 818 and VL 840, respectively. Significantly higher green fodder yield (69.32 q/ha) was obtained from VL 818 than under VL Gehun 616 and VL Gehun 829, while it was at per with fodder yield of VL 840. Cutting of green fodder scheduled at 70 and 85 DAS resulted no significant difference in yield. However, it showed the possibility of extended availability of green fodder without affecting the production the grain and straw yield obtained under VL Gehun 829 (60.05 q and 121.5 q/ha, respectively) were statistically superior to VL Gehun 616 and VL 818 and at par with VL 840. Harvest of green fodder affected grain yield of wheat up to 7% through it was not statistically significant. Therefore, it can be concluded that among the different cultivar VL Gehun 829 and VL 840 are the most suitable for dual purpose and can be cut after 70 and 85 DAS for green fodder as both stage of cut produced at par green fodder, grain and straw yields, thereby ensuring fodder and food security in the region.

The present paper reports that significant genetic variability was evident in Fe, Zn, β-carotene, and phytic acid (phytate, PA) contents in a set of 39 diverse maize genotypes collected from maize breeding programme of hill agriculture, India. The Fe, Zn, β-carotene, and PA concentrations were found to be in the range 19.31–50.64 mg kg−1, 12.60–37.18 mg kg−1, 0.17–8.27 µg g−1, and 6.59–7.13 g kg−1, respectively. The genotypes V335, V420, V393, V416, V414, V372, and V351 were identified to have higher concentration of β-carotene, Fe, and Zn but lower amount of PA. Possible availability of the minerals Fe and Zn was determined using molar ratio between PA as inhibitor and β-carotene as promoter for their absorption. The micronutrient molar ratio showed that Fe and Zn traits could be dependent of each other. Low R2 value revealed relation between β-carotene and kernel colour. The selected genotypes could be considered as potential sources of favourable genes for further breeding programs to develop micronutrient enriched maize cultivars.
