Item Influence of the method of application of N and P on the growth, yield and quality of blackgram [Vigna mungo (L.) Hepper](Department of Agronomy, College of Agriculture, Vellayani, 1983) Elizabeth K Syriac; Chandrasekharan, PItem Nutritional requirement of green gram (Vigna radiata (L.) Wilczek(Department of Agronomy, College of Agriculture, Vellayani, 1980) Savithri, K E; Madhavan Nair, K PAn experiment was conducted In the Instructional Farm, College of Agriculture, Vellayni during 1979 to study the effect of three levels in each of nitrogen (20, 30 and 40 kg/ha), phosphorus (30, 45 end 60 kg/ha) and potash (10, 20 and 50 kg/ha) on growth, yield and quality of green gram (Vlgna radiata) grown in rice fallows. The experiment was laid out as 3 partially confounded factorial experiment with two replications, confounding NPK in replication I and NPK2 in replication II Tho study revealed that nitrogen, phosphorus and potash had on influence on height and number of leaves, but not on nodulatlon. The yield contributing factors sanely number of flowers sad number of pods per plant, length of pod and number of seeds per pod ware not influenced by the treatments, Weight of seeds per plant was significantly increased by the highest level of potash and 100 seed weight by higher levels of phosphorus, while highest level of nitrogen significantly decreased tho 100 seed weight. Maximum grain yield of 538 kg/ha was obtained with the highest level of potash.Dry natter yield was also influenced by potash and bhusa yield by nitrogen.Item Nutritional requirement for horsogram (Dolichos biflorus Roxb.)(Department of Agronomy, College of Agriculture, Vellayani, 1984) Kumari Swadija, O; Chandrasekharan, PA field experiment was conducted at the college of Agriculture, Vellayani during 1932 to study the effect of three levels each of nitrogen (0.15 and 30 kg/ha), phosphorus (0. 25 and 50 kg P2Os/ha) and potassium (0.20 and 40 k2O/ha) on growth, yield and quality of horsegram. The trial was conducted as a 3 partially confounded factorial experiment with two replications. Application of nitrogen phosphorus and potassium had profound influence on all growth characters like height of plant* number of functional leaves and branches per plant and leaf area index. The highest nodule count was obtained by the application of 15 kg N 25 kg Pg 5 and 20 kg KO per hectare while tho dry weight of nodules per plant was maximum at 15 kg N 50 kg 40 kg K2O per hectareItem Nutritional requirement of black gram {Vigna mungo (L) Hepper}(Department of Agronomy, College of Agriculture, Vellayani, 1980) Annamma George; Madhavan Nair, K P
