A field experiment was conducted from rabi 2000 to kharif 2008 to study the effect of different forage based cropping systems on productivity, sustainability, nutrient use productivity, monetary efficiency and soil properties under mid hill conditions of north-western Himalaya. Eight cropping systems were tested in randomized block design with three replications. Oat (Avena sativa L.) + fodder sarson (Brassica rapa L.) - fodder maize (Zea mays L.) + fodder cowpea (Vigna unguiculata (L.) Walp.) cropping system resulted in highest green fodder equivalent yield (60. 77 t/ha/year) with better production efficiency (166 kg/ha/day) and sustainable yield index (0.99). In terms of net returns, wheat - fodder maize cropping system maintained superiority (Rs.39,676/ha/year) with monetary efficiency of Rs.109/ha/day. Systems comprised of short duration crops and legumes, resulted in improvement in available soil NPK. However, inclusion of sorghum and guinea grass in the cropping system did not improved soil nitrogen status even after the completion of eight crop cycles.Keywords

Two formulations of isoproturon viz. arelon and isoking (1.0 and 1.25 kg a.i./ha) each with 2,4D (0.75 and 1.0 kg/ha) as tankmix and sequence application along with farmers' practice and untreated check were evaluated for weed control in wheat during 200607 and 200708 at Palampur. Phalaris minor (42.6%), Avena ludoviciana(25.1%), Lolium temulentum (11.1%), Vicia sativa, (7.6%), Anagallis arvensis (9.6%), and Coronopus didymus (4.0%) were the major weed species and reduced wheat grain yield by 38.7%. Tankmix application of isoking + 2,4D effectively controlled P. minor, A. ludoviciana and L. temulentum and were on par with farmer's practice. Arelon 1.0 kg a.i./ha + 2,4D 1.0 kg/ha resulted in lowest count of Vicia sativa, while isoking 1.0 kg a.i./ha + 2,4D 1.0 kg/ha resulted in lowest count of Anagallis arvensis. All herbicidal treatments were significantly superior to farmers' practice in controlling C. didymus. Isoking 1.0 kg a.i./ha + 2,4D 1.0 kg/ha recorded highest weed control efficiency (71.5), treatment efficiency index (1.93), crop resistance index (5.0) and resulted in highest grain yield, net returns (Rs. 14373/ha) and marginal benefit:cost ratio (13.2). Isoking 1.25 kg a.i./ha + 2,4D 0.75 kg/ha had highest weed management index, agronomic management index and integrated weed management index.Keywords
