“…The present results are in conformity with those of Torres et al, (2016) and Man et al, (2017). Based on this study, it can be concluded that cultivation of castor variety PCH 111 and GCH 4 with 120 kg N ha -1 has recorded higher growth and yield parameters and bean yield in Andhra Pradesh under rainfed condition.…”

“…The yields that were obtained, especially those in the KL and KH treatments, are higher than those reported by Shinde et al (2018) and Man et al (2017) and are even comparable with those obtained by the fourteen genotypes studied by Shah et al (2017). These yield results are believed to be partly due to the adequate development of the castor plant photosynthetic apparatus (90-133 DAS) and partly due to the formation of photosynthates and their translocation towards flowering and the formation and filling of fruit, rather than towards the formation of other plant parts, such as more vegetative area, as in the case of the Rincon variety.…”

This study discusses how soil moisture influences the seed yield of two castor plant varieties in an arid zone in Mexico. An experiment was set up with two factors: soil moisture, with three levels (high = -0.05 MPa, medium = -0.31 MPa and low = -0.91 MPa), and castor variety (Krishna and Rincon). The combination resulted in a factorial 3 × 2 experimental design. The experiment was set up as a randomized block with four replications under a split-plot arrangement, where the whole plots were for soil moisture and the subplots were for the castor variety. The measured variables were plant height (PH), days to flowering of 50% of the plants (DF), leaf area (LA), dry weight (DW), source-sink relationship, harvest index (HI) and seed yield. Data were analyzed by ANOVA, mean tests (HSD at α = 0.05) and regression analysis. There were significant differences in PH, LA, DW, HI and yield among the treatments. The values of PH, LA and DW tended to be higher at higher soil moisture levels than at lower moisture levels. The source strength was generally lower than the sink strength in all the treatments. There were significant differences between the varieties for HI, and the interaction between soil moisture and variety was also significant. Significant differences were found in yield; the Krishna variety had a greater yield than the Rincon variety, but there was only a significant difference between the yield of the Krishna variety cultivated under low soil moisture (5200 kg ha -1 ) and that of the Rincon variety cultivated under high soil moisture (2570 kg ha -1 ). The results of this study indicate that castor plants can be cultivated in arid regions at suboptimal soil moisture levels with supplementary irrigation without compromising plant performance or yield.

A field experiment was conducted at Main Oilseeds Research Station, Junagadh Agricultural University, Junagadh (Gujarat) during kharif season of 2013-14 to 2015-16. The soil was medium black and clayey in texture.The experiment was laid out in Split Plot Design comprising four levels of plant geometry (G1:150 cm x 90 cm, G2: 150 cm x 60 cm, G3: 120 cm x 90 cm and G4: 120 cm x 60 cm) allotted to main plots and four potassium levels (K1:Control, K2: 20 kg K2O/ha, K3: 40 kg K2O/ha and K4: 50 kg K2O/ha) assigned to sub plots and replicated thrice. The results indicated that castor sown at 150 cm x 60 cm and 120 cm x 60 cm spacing recorded significantly higherplant population, plant height, number of branches, number ofspikes, length of main spike, number of capsules per spike and seed yield in pooled results. While, almost all the growth characters, yield attributes, quality parametersand seed yield were found significantly higher when crop was fertilized with 40 and 50 kg K2O/ha. Interaction effect between crop geometry and potassium levels was significant and crop geometry of 120 cm x 60 cm with potassium application @ 40 kg K2O/ha (G4K3) recorded significantly higher castor seed yield (3714 kg/ha) and net return (`1,01,290/ha) with B:C ratio of 3.81. It was concluded that kharif castor should be sown at 120 cm x 60 cm with an application of potassium @ 40 kg K2O/ha along with recommended dose of nitrogen and phosphorus (120-50 kg NP/ha) for obtaining higher seed yield and net return.
