  The effect of bunch and flat plantation on the yield and fibre quality of a hirsutum cotton genotype NIAB-26 was determined. The treatments comprised 100 cm apart 100 x 100 cm pit plantation with a bunch of 5, 7 and 9 plants per pit, 60 x 60 cm hills with two plants per hill, 90 cm spaced double-row strips (30/90 cm) and 60 cm spaced single rows. The results revealed that although bunch plantation in 100 cm apart 10 x 100 cm pits improved the fruiting potential and boll size to a significant extent but did not compensate the yield loss due to lower plant population per unit area compared to flat plantation with a normal plant population The highest seed cotton yield of 3637 kg ha-1 was obtained from flat plantation in 90 cm spaced double-row strips (30/90 cm) against the lowest of 1675 kg ha-1 from pit plantation with a bunch of 5 plants per pit.

  The seeding rates were 100 and 150 kg ha–1 while the nitrogen levels comprised 100, 150 and 200 kg ha–1 with five split application treatments viz. full at sowing, full with first irrigation, half at sowing and half with first irrigation, two third at sowing+one third with first irrigation and one third at sowing+One third with first irrigation+one third with second irrigation along with a basic dose of 100 kg ha–1 each of P and K applied at sowing. The crop was planted on December 19. The highest grain yield of 3585 kg ha–1 was obtained from plots given nitrogen full at sowing at 150 kg ha–1 followed by 3334 kg ha–1 in plots given nitrogen in two splits i.e., two third at sowing and one third with first irrigation. However, higher seeding rate (150 kg ha–1 ) tended to increase grain yield ha–1 with a nitrogen rate of 150 kg ha–1. By contrast, grain protein contents were the highest (12.26%) in crop fertilized with 150 kg ha–1 full at sowing and seeded at 100 kg ha–1.

  The intercropping proportions comprised 100 cm spaced 4-row strips of linseed intercropped with one, two , three and four rows of methra along with sole cropping of the component crops. Intercrop was sown between the strips of linseed at the time of planting linseed. Different yield components of linseed were invariably influenced significantly by the associated methra crop in different proportions. The yield of linseed intercropped with one, two, three and four rows of methra was reduced by 6.94 6.92 8.46 and 18.36 per cent respectively. However , at the cost of this much reduction in linseed yield an additional harvest of 156, 220, 326 and 379 kg ha-1 of methra was obtained from the respective intercropping patterns which compensated more than the losses caused in the yield of linseed. The highest total grain yield of 1223 kg ha-1 was recorded for linseed + three rows of methra intercropping system against the minimum of 980 kg ha-1 in case of linseed + one row of methra intercropping pattern. By contrast, the highest net income (Rs.7665 ha-1 ) was obtained from an intercropping pattern of linseed + four rows of methra against the minimum (Rs.3683 ha-1 ) in case of sole cropping of linseed. On the whole linseed-methra intercropping in different proportions gave 17 to 38 per cent yield advantage over mono cropping of the component crops with the maximum (38 %) in linseed + three rows of methra intercropping pattern.
