-1 , T 4 = Vermicompost @ 5 t ha -1 , T 5 = Mustard cake @ 2.5 t ha -1 , T 6 = Mustard cake @5 t ha -1 , T 7 = Poultry manure @ 2.5 t ha -1 , T 8 = Poultry manure @ 5 t ha -1 , T 9 = F.Y.M @ 8 t ha -1 , T 10 = RDF +FYM @ 4 t ha -1 , T 11 = Vermicompost @ 2.5 t ha -1 + mustard cake @ 2.5 t ha -1 , T 12 = Vermicompost @ 2.5 t ha -1 + mustard cake @ 5 t ha -1 , T 13 = Vermicompost @ 2.5 t ha -1 + F.Y.M @ 4 t ha -1 and T 14 = Vermicompost @ 2.5 t ha -1 + mustard cake @ 2.5 t ha -1 + poultry manure @ 2.5 t ha -1 + F.Y.M @ 4 t ha -1 . Poled data revealed that seed yield of buck wheat were increased by 5.2 and 12.8 quintal ha -1 through combine application of vermicompost @ 2.5 t ha -1 + mustard cake @ 2.5 t ha -1 + poultry manure @ 2.5 t ha -1 + F.Y.M @ 4 t ha -1 over 100 % RDF and control. Combined application of vermicompost @ 2.5 t ha -1 + mustard cake @ 2.5 t ha -1 + poultry manure @ 2.5 t ha -1 + F.Y.M @ 4 t ha -1 (T 14 ) recorded significantly higher percentage of starch (72.1 and 72.1) and protein (14.2 and 14.4) during 2012 and 2013, respectively which was followed by combined application of vermicompost @ 2.5 t ha -1 + mustard cake @ 5 t ha -1 (T 12 ) and poultry manure @ 5 t ha -1 (T 8 ). The highest benefit: cost (2.96) was noticed in T 8 (Poultry manure @ 5 t ha -1 ) followed by T 2 (2.83).

The field experiments were carried out at Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India during summer seasons of 2012 and 2013, to study the effect of weed management on growth and yield of groundnut (Arachis hypogaea L.) in gangetic plains of West Bengal. Weed biomass, weed control efficiency as well as the pods plant -1 , 100-seed weight, seed yield were significantly affected due to weed control treatments. Treatment receiving hand weeding twice recorded lowest weed biomass (3.44 g m -2 ) and highest WCE (85.09 %). Highest seed yield (1025 kg ha -1 ) was also recorded with hand weeding, which was significantly higher over other treatments. The results also showed that oxyfluorfen and chlorimuron-ethyl treatment applied at recommend rate were also effective in reducing the dry weight of weeds. Further the tested herbicides did not have significant effect on the crude protein and oil content in seeds.

In the coastal region, farmers view their farming operation as a system in which crop and fisheries are integral parts. The paper has studied the impact of some land-shaping interventions implemented through crop-fish integration. The paper has found that these land shaping models-farm pond, paddy-cum-fish, deep-furrow & high ridge and broad bed & furrow system-have created the land suitable for growing multiple crops and rearing fish. Financial analysis of these land shaping models has indicated that investment on such interventions are financially viable (IRR, 36-48%; NPV, ` 0.97-3.67 lakhs; BCR, 1.20-1.58; and payback period, 1.41-2.13 years) and attractive proposition for the coastal region in Sundarbans and Andaman & Nicobar Islands. For out-scaling of these technologies on a wider scale, there is a need to address some socioeconomic constraints and provide policy support. The proposition of crop-fish integration in agriculture through these land-shaping models has been found quite suitable for enhancing the income and employment in the costal region of India.
