  In a field trail at Faisalabad, fodder yield and quality of sorghum (Sorghum bicolor L.) cultivar JS-263 as influenced by different nitrogen levels (0, 50, 100 and 150 kg ha -1) and harvesting times (45, 60 and 75 days after sowing) was studied in 2000. Both green and dry matter yields were increased with increasing nitrogen levels and delaying harvest. The increase in yield was mainly due to higher plant height, stem diameter and number of leaves plant -1. The contents of crude protein, ether extractable fat and ash were increased with increased nitrogen levels and decreased with delaying the harvest. Whereas, neutral and acid detergent fiber were increased by delaying the harvest and decreased by the nitrogen application. Based on these finding, the nitrogen level of 150 kg ha -1 and harvesting time 75 days after sowing was found better combination for getting higher yields of sorghum cultivar JS-263 under Faisalabad conditions.

  Competition functions of different intercropping systems i.e. canola, wheat gram, lentil and linseed were compared with sole cropping of canola for two consecutive years under the field conditions. Competition behaviour of component crops across different intercropping systems and planting patterns was determined in terms of relative crowding coefficient, aggressivity and competitive ratio. Relative crowding coefficient (RCC) reflected that maximum K (4.08) was obtained from canola+one row of wheat intercropping system. Aggressivity (A) values –0.03 and 0.06 indicated that wheat was the most competitive crop to canola. Similarly, competitive ratio (CR) 0.82 and 0.51 showed that among intercrops, wheat proved to be a better competitor than other intercrops when grown in association with canola.

  Agro-economic advantages of different intercropping systems i.e. canola+one row of wheat, canola+two rows of wheat, canola+one row of gram, canola+two rows of gram, canola+one row of lentil, canola+two rows of lentil, canola+one row of linseed and canola+two rows of linseed were compared with sole cropping of canola for two consecutive years under field conditions. Canola seed yield equivalent, land equivalent ratio, area-time equivalent ratio and net income values of canola+one row of wheat intercropping system was higher than the other intercropping systems and sole cropping of canola.

  Five substituted area based herbicides namely Isoproturon (Alrelon 500 FW), Isoproturon + Diflufenican (Panther 520 FW) Isoproturon + Bromoxynil + MCPA (Doublet 48 FW), Chlortoluron + MCPA (Agmol combi 60 WP) and Isoproturon (Milron 75 WP) applied @ 2.5 1, 2.0 1, 2.5 1, 2.5 kg and 1.25 kg ha -1, respectively, controlled, 87.2 to 90.8 per cent weeds in wheat and caused 10.29 to 15.98 per cent increase in grain yield over weedy check. These herbicides, when applied with 3 per cent urea solution, gave 92.6 to 95 per cent weed control and 19.24 to 25.47 per cent increase in grain yield over weedy check.

  Studies to evaluate the effect of different planting patterns and seed densities on the growth and yield performance of rice bean were conducted during 1997-98. The planting patterns were 60 cm apart single rows, 90 cm apart double row strips (30/90), 60 cm apart ridge sowing and 90 cm apart bed sowing with seeding densities of 20, 25 and 30 kg ha -1. The results revealed that different growth and yield parameters were significantly influenced by different planting patterns and seed rates. The treatment combination of S2P3 (25 kg ha -1 seed under 60 cm ridge sowing) produced the highest grain yield of 1191.0 kg ha -1 and differed significantly from rest of all the treatment combinations.
