“…The survey results showed that pests and diseases attack and non-adoption of plant protection measures on the part of tribal farmers as one the major factors for lower productivity of castor bean which accounted for the loss of yield to the tune of 300 kg/ha which is in conformity with earlier results reported by Ramanjaneyulu et al (2014) followed by uneven distribution of rainfall (250 kg/ha). Other factors like non-availability of agricultural inputs like implements, labour, etc.…”

Castor bean is one of the prominent industrial oilseed crops grown in India. It is confined to mostly Gujarat, Rajasthan and Andhra Pradesh (undivided AP). Castor is also grown on a limited scale in the states of Karnataka, Tamil Nadu, Maharashtra, Orissa and Madhya Pradesh. The crop is known as poor man's crop and mostly confined to Mahabubnagar, Rangareddy and Nalgonda of Telangana while Prakasam, Anantapur and Kurnool districts of Andhra Pradesh. In Telangana and AP, castor bean is cultivated under rainfed condition during kharif season and the productivity varies from 440-675 kg/ha, which is far below than the national average of 1512 kg/ha (DOR, 2012). The data on area, production and productivity of castor in AP (undivided) and Mahabubnagar are given in Tables 1 and 2. Data in Table 2 indicate that the productivity levels of Mahabubnagar district over years varies from 420 to 550 kg/ha, which is less than the state average.

“…Hence, growing castor as an irrigated dry crop (ID) during post monsoon season is a new dimension. In the recent times, the area under castor in post monsoon season is increasing in view of rise in demand for castor seeds due to multiple uses and also it's remunerative nature as compared to monsoon season castor and other competitive post monsoon season crops like groundnut, maize, jowar etc [9]. Among many agronomic aspects, identification of suitable cultivars and N management are very important for realising higher yields and returns.…”

Aim: The experiment is aimed at quantifying the nitrogen requirement and identifying suitable hybrids and varieties of castor to be grown during post monsoon season on Alfisols in Telangana Study Design: Split plot design. Place and Duration of Study: Regional Agricultural Research Station, Professor Jayashankar Telangana State Agricultural University, Palem, Telangana state, India during post monsoon season of 2010-11 and 2011-12. Methodology: The study consisted of four N levels (0, 40, 80 kg and 120 kg N ha-1) in main plots and five cultivars (DCH-177, PCH-111, GCH-4, Haritha and 48-1)in sub plots. The growth parameters, yield attributes, seed yield, water use efficiency, economic returns, correlation and regression were studied. Results: The pooled data indicated that significantly taller plants with more no. of branchesplant-1, longer and effective spikes thus seed yield of castor were observed due to application of 80 kg Nha-1 and 120 kg Nha-1. However, application of 120 kg N ha-1 resulted in greater net returns (USD 1049 ha-1) and also returns per rupee invested (1.66). The results further showed that the castor hybrids PCH-111 (1900 kg/ha) and DCH-177 (1809 kg/ha) produced similar yield, but, both significantly outyielded over other cultivars. The performance of hybrids was superior to the varieties. A highly significant positive correlation was observed for seed yield with no. of branches/plant, total and effective spike length. Conclusion: The cultivation of castor hybrids either PCH-111 or DCH-177 under N supply of 120 kg N ha-1 would help to realize higher yields, water use efficiency and income from post monsoon season castor on Alfisols.

“…under rainfed conditions during kharif season (June to September) in dry land tracts of South and Eastern India in general and in Telangana in particular. However, in view of incidence of Botryotinia gray mold, occurrence of frequent dry spells and less scope for life-saving irrigation due to meager water resources and consequent reduction in economic yields during kharif season in Telangana (Ramanjaneyulu et al, 2013), farmers are preferring to raise castor during rabi season (October to March) as an irrigated dry (ID) crop due to assured irrigation and higher yield thus better returns (Ramanjaneyulu et al, 2014). Further, groundnut is a popularly grown leguminous oilseed crop during rabi season in Telangana.…”

An experiment was carried out for three consecutive years from 2014-15 to 2016-17 at Regional Agricultural Research Station (RARS), Palem, Professor Jayashankar Telangana State Agricultural University, Telangana, India to study and understand the agro-economic feasibility and various indices of castor+groundnut intercropping system under irrigated conditions during rabi season. There were six treatments viz., sole castor, sole groundnut, castor+groundnut (1:5) with RDF (recommended dose of fertilizer) to both the crops, castor+groundnut (1:7) with RDF to both the crops, castor+groundnut (1:5) with RDF to castor alone and castor+groundnut (1:7) with RDF to castor alone. The results indicated that sole groundnut with significantly higher castor equivalent yield (3960 kg ha-1) gave a higher yield advantage by 12.5 to 25.8% over castor+groundnut intercropping and 102.5% over sole castor. Further, sole groundnut recorded higher water use efficiency (10.25 kg ha-1 mm-1) and net returns mm-1 water used (Rs. 243.65 mm-1). The economics also indicated that sole groundnut was profitable in terms of gross (Rs. 1,50,465 ha-1) and net returns (Rs. 94,150 ha-1). However, higher benefit:cost ratio was observed with sole castor (2.76) followed by sole groundnut (2.67) and castor+groundnut intercropping (1:5) with RDF applied to both crops (2.57). Among various indices, the highest land equivalent ratio (1.13), area time equivalency ratio (1.00) and monetary advantage index (15072) were recorded with castor+groundnut (1:5) where RDF was applied to both the crops.
