Effect of various plant growth substances viz., GA3 (25, 50,100 ppm), ethrel (1500, 2000, 2500 ppm), copper sulphate (0.1, 0.2, 0.5%) as foliar spray treatment applied during January to October was studied at 15 days intervals. The flowering behaviour and sex-expression of Jatropha curcas was investigated during in randomized block design (RBD) at the College Farm, Navsari. Looking to the results, it was noticed that GA3 50 ppm resulted in increased number of inflorescence per plant (31.25), number of flower per inflorescence (76.87), number of (male 94.75/female 4.01) flowers, flower sex ratio (24.22) in J. curcas. The Male: Female flower ratio was the lowest at 14th spray stage under majority of treatments indicating increased number of female flowers which is ultimately reflected by increased fruit and seed yield of J. curcas.

Background: The improvement in livestock productivity may be possible by availing better quality fodder in adequate quantity to the dairy farmers. Zinc deficiency might be a major factor for lower quality fodder of cowpea. Methods: The experiment was laid out in factorial randomized block design; comprised of three cowpea cultivars viz., C-152, MFC-08-14 and MFC-09-1 and five zinc management practices viz., control; 10 kg ZnSO4 as basal; 20 kg ZnSO4 as basal; 0.5% ZnSO4 as foliar spray at 20 DAS; 0.5% ZnSO4 as foliar spray at 20 and 40 DAS. Result: Results revealed that C-152 showed significantly better quality in terms of higher dry matter, crude protein and total ash; and lower acid insoluble ash, neutral detergent fibre, acid detergent fibre and acid detergent lignin amongst all the three varieties. Though, remarkably higher ether extract was obtained with MFC-08-14. Among the zinc management practices, 20 kg ZnSO4 as basal (Zn3) and foliar application of 0.5% ZnSO4 at 20 and 40 DAS (Zn5) recorded significant improvement in fodder yield and quality traits of cowpea.

Aim: To investigate the effect of KCl and KClO3 as sources of potassium in aerobic rice with four types of split doses and two levels of foliar applications of potassium. Study Design: The experiment was laid out in Randomized Block Design with three replications. Place and Duration of Study: Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, Puducherry. Methodology : The rice variety PMK 4 was tested with two sources of potassium viz., Potassium chloride (KCl) and Potassium chlorate (KClO3), four types of split application viz., K control (S1), basal with no split (S2), two splits (S3) and three splits (S4) along with foliar application treatments viz., no foliar (F1) and foliar spray (F2). Results: The results of a field experiment revealed that the two splits of potassium increased the available P at the active tillering stage and harvest stage. Whereas, three splits increased the available P at panicle imitation and flowering stage. The KCl recorded higher available P at panicle initiation and harvest stages. The high phosphorus uptake was recorded in panicle initiation and flowering stages by three splits application of potassium. In grain also, especially the three splits through KClO3 recorded higher P uptake. Conclusion: The split applications tested in this investigation influenced the available phosphorus status in soil and phosphorus uptake. Increase in splits of potassium increased the P uptake. This result is in agreement with the results of Mitra et al. [1] who observed a significant increase in the uptake of N, P, K and S by increased level of K in Kharif rice.

A field investigation was carried out to study the influence of zinc and iron micronutrients on the performance of rainfed castor, in Professor Jayashankar Telangana State Agricultural University, Telangana state, India for three consecutive years during kharif 2011-12, 2012-13 and 2013-14. There were nine treatments viz., Control (no micronutrient application); soil application of FeSO4 @ 15 kg ha-1; soil application of FeSO4 @ 25 kg ha-1; soil application of ZnSO4 @ 15 kg ha-1; soil application of ZnSO4 @ 25 kg ha-1; foliar application of 0.5% FeSO4 at 50 DAS; foliar application of 0.5% FeSO4 at 50 and 90 DAS; foliar application of 0.5% ZnSO4 at 50 DAS; foliar application of 0.5% ZnSO4 at 50 and 90 DAS and tested in randomized block design with three replications. The foliar application of ZnSO4 (0.5%) twice at 50 and 90 DAS resulted in significantly higher seed yield (1698 kg ha-1), higher gross returns (Rs. 54344 ha-1), net returns (Rs. 33501 ha-1) and B:C ratio (2.60) over rest of the treatments. The seed yield improvement was to the tune of 54% over no micronutrient application. The uptake of major and micronutrients was greater when the crop received two sprays of ZnSO4 as compared to one spray of ZnSO4, two sprays of FeSO4 and soil application of either of the micronutrients. The castor bean crop responded to Zn better than Fe by producing 10.2% to 12.2% higher seed yield. Foliar spray was found superior to soil application in case of both the micronutrients.
