Green gram (Vigna radiata (L.) wilczek,) commonly known as moong or mung bean or golden gram was introduced to Eritrea as a pulse crop by Ministry of Agriculture at its National Agricultural Research Institute (NARI) in collaboration with Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA) in 2012. But its agronomic practices for semi-arid conditions of Eritrea are not yet standardised. Therefore , to find the optimum inter row spacing and phosphorus dose for its higher productivity ,a field experiment was conducted at the experimental farm of Hamelmalo Agricultural College, Keren, Eritrea during summer 2015 and 2016. The experiment was conducted in randomised complete block design (RCBD) with 12 treatment combinations of two factors consisting of four inter row spacing (Broadcast, 18cm, 30cm, and 45cm) and three phosphorus levels (0, 20 and 40 kg P2O5 ha-1) each replicated thrice. The results of the study revealed that sowing of K-26 bold seeded variety either by broadcast method or at 18cm inter row spacing at10cm plant to plant spacing fertilized with 40kg P2O5 ha-1 through DAP fertilizer drilled at the time of sowing proved significantly superior to increase growth, yield attributes and seed yield of green gram.

The atmospheric CO2 will be in the range of 510 to 760 L-1 by the end of 21st century and mean global temperature will be 1.5 to 4.5 oC higher than the present day which has a direct and indirect effect on agriculture. India is a key global region vulnerable to climate change; however, limited studies have focused on the combine effect of CO2 enrichment and temperature on wheat production in Sub-humid climate of eastern IGP in India. To address this issue, an Open top chamber (OTCs) experiment was conducted during 2013-14, to determine the effects of elevated atmospheric carbon dioxide (CO2) and temperature on growth, yield attributes and yield of wheat. Wheat cultivars (DBW 14 and HD 2967) were grown with four treatment combination of CO2 and temperature in OTCs, during the rabi season. The study revealed that wheat genotypes performed better under elevated CO2 condition in term of grain number, test weight and grain yield than an ambient condition. The greater biomass under elevated CO2 was brought about by an increase in radiation use efficiency (RUE) during both heading and physiological maturity periods. Elevated temperature decreased the grain yield but increase plant height compared to ambient temperature. Days to physiological maturity was reduced by 4 to 7 days in both the cultivars under elevated temperature condition and increased by 3 to 4 days under the elevated CO2 condition with respect to ambient condition. The elevated CO2 had positive effects whereas elevated temperature had negative effects on growth, yield attributes and yield of wheat. With elevation of both CO2 and temperature, elevated CO2 compensate the negative effects of elevated temperature on growth, yield attributes and yield of wheat.

SUMMARYResults are described of an experiment conducted for 2 years in North-West India where grain legumes increased the N and P status of the soil compared with cereal or fallow. Maize following legumes recorded increases in growth, yield attributes, yield and N uptake. Various winter grain legumes such as chickpea, lentil, pea and Lathyrus sativus reduced the need for fertilizer N in maize to the extent of 18–68 kg/ha compared with cereal (wheat) or fallow. Application of nitrogen to the maize promoted plant growth and increased both yield and N uptake.
