  A field experiment of hedgerow intercropping of pigeonpea with rice and mungbean followed by blackgram and groundnut, respectively, as alley crops was conducted to determine the effect of hedgerow crop on the yield of alley crops, the productivity of hedgerow crop and its contribution to the alley crops. Alley cropping of rice-blackgram and mungbean-groundnut crop sequences with 1.5 and 2.5 m hedgerow distance of pigeonpea along with sole cropping sequences were evaluated. Grain yield of all crops were affected by hedgerow intercropping systems. Significantly highest rice equivalent yields and gross returns were obtained by hedgerow intercropping systems with 2.5 m hedgerow distance for both the crop sequences in both 1995 and 1996. The highest gross margin and the highest benefit-cost ratio (BCR) were resulted from hedgerow intercropping at 2.5 m distance with rice-blackgram crop sequence and the system was found profitable.

  Protoplasts were isolated from cotyledons, hypocotyls and cell suspensions of agriculturally important species of jute (C. olitorius). Maximum protoplast yields were obtained from cotyledons. Protoplasts of all sources of C. olitorius divided only in K8P medium. Yield and viability of protoplasts were influenced by mucilage secretion in the enzyme solution during incubation. Mucilage secretion was almost eliminated by regulating the growth conditions of the seedlings such as high temperature (28 oC) and continuous illumination (1.0 W m -2 of daylight fluorescent illumination). Rhizogenesis was obtained from cotyledon protoplasts. Attempts to regenerate shoots from protoplast-derived calli and roots failed.

  A study was conducted with a view to predict the correlated response in yield taking plant height as the criterion for single trait phenotypic selection in jute. Results indicated that selection on plant height did not reflect a corresponding response in yield. Application of high selection intensity may be risky. So a low intensity selection on plant height should be applied when selection is done based on plant height only. In such situation, yield estimation of the plants above mean height may increase selection efficiency. But for higher yield direct selection appeared to be efficient over indirect selection.

  Studies were provided evidence that as density of plant increased seed yield decreased and number of pods per plant, number of seeds per plant, number of seeds per pod, seed weight per plant and 100 seed weight all decreased. High density also produced the poorest quality pea seeds. There were no differences in germination percentage of the seeds produced from the main stem. However, the seeds produced from the branches showed a variation in germination. The germination percentage was similar in the lower nodes but in the upper nodes of the branches showed a lower germination percentage.
