Microirrigation and establishment methods for water use studies, fodder yields and postharvest available nutrients on Bajranapier hybrid grass [CO (BN) 5]

The availability of quality fodder is becoming a major concern in India. To address this, a field experiment was conducted on bajranapier hybrid grass CO (BN) 5 (Interspecific hybrid between Cumbu (Pennisetum glaucum) and Napier (P. Purpureum Schumach) during 2018-19 in strip plot design with 3 replications. Treatment comprises of main plot viz., Irrigation methods sub plot viz., Crop establishment methods. The results showed that in water use studies, higher WUE (23.74 t/ha/mm) was recorded with sbsurface drip irrigation. Similarly, higher water productivity (WP) (0.024 t/m3) and economic WP (474.78 ₹/ha/mm) were also with the same. In crop establishment methods, horizontal planting of setts with settling treatment recorded higher WUE (21.47 t/ha/mm), WP (0.021 t/m3) and economic WP (429.43 ₹/ha/mm). Significantly higher (0.05 %) green (335.0 t/ha/year) and dry fodder yields (71 t/ha/year) were registered with subsurface drip irrigation (M3). In crop establishment, horizontal planting of setts with settling treatment (S2) registered higher green (331.5 t/ha/year) and dry (71.4 t/ha/year) fodder yields.On postharvest soil available nutrients, higher N (172.3 kg/ha), P (22.2 kg/ha) and K (591.5 kg/ha) were observed with surface irrigation. Vertical planting of setts without settling treatment recorded higher N (172.1 kg/ha), P (23.3 kg/ha) and K (604.8 kg/ha). By adopting this subsurface drip irrigation with horizontal planting of setts with sett treatment, the bajranapier hybrid grass cultivation can be optimized for the betterment of cultivation

Factors Responsible for the Stability and the Existence of a Clean Energy Gap of a Silicon Nanocluster

We present a critical theoretical study of electronic properties of silicon nanoclusters, in particular the roles played by symmetry, relaxation, and hydrogen passivation on the the stability, the gap states and the energy gap of the system using the order-N [O(N)] non-orthogonal tight-binding molecular dynamics and the local analysis of electronic structure.Comment: 26 pages including figure
