EVALUATION OF DEFOLIANTS ON MUNGBEAN Vigna radiata L. AS HARVESTING TOOLS treatment (Rs. 2,450/- per ha) due to increased labour efficiency because of less interference of leaves in harvesting of pods (Table 1). These results corroborate with the findings of Rajni et al. (2011) in Bt cotton. Thus herbicidal defoliants can be successfully applied for aiding the harvest of mungbean. REFERENCES Bi G, Scagel, C.

Research Notes J.Res. ANGRAU 41(2) 118-122, 2013 YIELD, NUTRIENT UPTAKE AND ECONOMICS OF CASTOR AS INFLUENCED BY INTEGRATED NUTRIENT MANAGEMENT IN PONGAMIA + CASTOR AGRISILVISYSTEM K. INDUDHAR REDDY, S. HEMALATHA, G. JAYASREE and V. PRAVEEN RAO Department of Forestry, College of Agriculture, Rajendranagar, Hyderabad- 500 030 Date of Receipt : 04.07.2012 Date of Acceptance : 05.03.2013 One of the need based alternative land use system replacing the traditional farming system is a tree based system of cropping i.e., agroforestry which acts as sustainable land management system especially in dry land areas. Pongamia pinnata is a multipurpose tree species (MPTS) and it is a good nitrogen fixing tree also. This tree species is sustainable for agroforestry farming because of its fast growth and nitrogen fixation. It is the best suited tree for energy plantations. Since the gestation period is high in Pongamia and because of wider spacing between the trees the interspaces can be effectively used for intercropping. Castor (Ricinus communis L.) being one of the important non edible oil seed crop of the country and also A.P., is largely cultivated under rain fed condition. Castor is the second most important oilseed crop of Andhra Pradesh in terms of acreage and economy after groundnut. The average yields of the crop were 1346 kg ha -1 and 510 kg ha -1 for India and Andhra Pradesh respectively (CMIE, 2010) which was regarded as very low though occupying first rank in area in the country. For improved production of castor, application of required quantities of fertilizer is imperative through sustained soil health. Soil fertility build up through agroforestry and practice of integrated nutrient management were suggested as potential means to increase the soil fertility especially in dry lands (Reddy et al. 1993).For efficient production and management of castor in dry lands it is necessary to seek alternate practices like integrated nutrient management and soil and moisture conservation. Keeping these facts in view, a comprehensive study is therefore planned in which different combinations of organic manures and inorganic fertilizers were applied to Pongamia + Castor agrisilvi system. The experiment was conducted during Kharif 2010-11 in alfisols at students’ farm, College of Agriculture, Rajendranagar, Hyderabad. The soil was red sandy loam in texture and neutral in soil reaction, low in organic carbon and available nitrogen and medium in available phosphorous and potassium. The experiment was laid out in Randomized block design with three replications and nine treatments viz., T1- Control; T2-100% Recommended Dose of Nitrogen (RDN) (Inorganic);T3-75% RDN (Inorganic); T4-75% RDN (Inorganic) + 25% RDN (FYM); T5-75% RDN (Inorganic) + 25% RDN (Neem cake); T6-75% RDN (Inorganic) + 12.5% RDN (FYM) +12.5% RDN (Neem cake); T7-50% RDN (Inorganic) + 25% RDN (FYM); T8-50% RDN (Inorganic) + 25% RDN (Neem cake); T9-50% RDN (Inorganic) + 12.5% RDN (FYM) +12.5% RDN (Neem cake) and the requisite amount of nitrogen was applied through urea as per the treatments based on the recommended dose i.e., 60 kg N ha -1 . The nitrogen was applied in three equal splits, first dose as basal and the remaining doses at 30 and 60 days after sowing (DAS). Whereas uniform dose of 40 kg P 2 O 5 and 30 kg K 2 O per hectare were applied through single superphosphate and muriate of potash respectively as basal dose to all the experimental plots. The amount of rainfall received during crop growth period (877.8 mm in 55 rainy days) was adequate for normal growth of crop. The vegetative stage of crop was healthy due to uniform distribution of rains but the incessant rains received during crop growth coincided with flowering and capsule formation stages and contributed to severe incidence of castor semilooper and Botrytis, this in turn affected the seed yield of castor drastically and hence low yields were recorded in this experiment.
