SUMMARYExperiments made with winter fodder crops, lucerne (Medicago sativa), berseem (Trifolium alexandrinum) and oats (Avena sativa) and summer fodder crops, cow pea (Vigna unguiculata), guar (Cyamopsis tetragonoloba), sunhemp (Crotolaria juncea) and pearl millet (Pennisetum americanum) showed that a sequential crop of Sudan grass yielded more after the legumes than after the cereal fodders, oats or pearl millet. The legume advantage was noted in the crop not given fertilizers but also when Sudan grass was given N fertilizer. The yield increase in Sudan grass grown after legumes was equivalent to 32–60 kg fertilizer N/ha applied to Sudan grass following pearl millet.After harvesting the legumes more available N and NO3-N was present in the soil and the apparent recovery of fertilizer N by a subsequent crop was increased by the legume.

Background: Organic production of cluster bean is to contribute to the enhancement of production sustainability along with ecology. Sustainability in organic farming must therefore be seen in a holistic sense, which includes ecological, economic and social aspects. A synergistic effectof bio fertilizer with crop increases the crop productivity and sustainability also. Bio fertilizers are low cost, effective and renewable sources of plant nutrients to supplement chemical fertilizers. Therfore to overcome the ill effect of chemical based farming, organic system is becoming the emerging need of the society.Methods: A field experiment ’’was carried out in Pusa Navbahar variety of clusterbean during summer season (February to May) of 2019 at College farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Dist. Mehsana, Gujarat, India. Sixteen treatments having various combinations of organic sources of nutrients (FYM, vermicompost, and neem cake), bio fertilizers (Rhizobium + PSB + KSM) along with RDF (20/40/0 kg/ha) as a control. They were replicated thrice in a randomized block design having a plot size of 3.0 m × 2.0 m with a spacing of 60 cm × 20 cm. Standard practices were followed during the entire course of the investigation.Result: It showed highly significant differences among different treatments for majority of the growth and yield attributing traits, but treatment T6 (75% N through FYM + Rhizobium + PSB + KSM) was rated as the best treatment for characters like days taken for germination, number of root nodules per plant, plant height at 60 DAS (cm), number of pod per cluster, number of cluster per plant, green pod yield per plant (g), green pod yield per plot (kg) and green pod yield per hectare (kg) as compared to other treatment. It can be concluded that the organic nutrient management in cluster bean with the application of 75% N through FYM + Rhizobium + PSB + KSM is beneficial for obtaining a higher yield.

Background: The present germplasm of cluster bean lack the needed natural variability for developing early maturing short statured lines. Therefore, an attempt was made to study the magnitude of heritable variability stimulated through induced mutation in M3 generation. Methods: M3 generation seeds of cluster bean variety MDU1 treated with gamma rays, electron beam and combination of gamma ray with EMS were used in the present investigation. The biometric observations were recorded on ten selected M3 plants from each family of every treatments for six traits viz., plant height, days to first flowering, number of clusters per plant, number of pods per plant, pod length and pod yield per plant. The same method was followed for recording observations on untreated parental materials also. Result: Studies on the variability parameters indicated that the phenotypic variance, genotypic variance, heritability and genetic advance were higher in combination treatment for all the traits. The shortest mutant and the earliest flowering (3M11) was observed in combination of 100 Gy of gamma ray+20 mM EMS. Mutant for the highest number of clusters (3M3) was observed in combination treatment of 300 Gy gamma ray with 20 mM EMS. The mutants for the highest number of pods per plant (3M1 and 3M2) and the highest pod yield (3M1) were identified at 400 Gy of gamma ray treatment. Fifteen desirable mutants were selected and forwarded to next generation for testing the stability in different environments.
