Growth and Yield of Sesame (Sesamum indicum L.) under the Influence of Planting Geometry and Irrigation Regimes

Abstract A. Nadeem et al. 981 particularly seed yield (765.00 kg•ha −1 ), whereas minimum traits were noted in the interaction of planting geometry of 30 × 20 cm × two irrigations (20 and 40 DAS). Furthermore, the results of four and three irrigations had non-significant differences with each other means not sharing the same letter differ significantly at 0.05 probability level. Hence, it is concluded that interaction of 45 × 15 cm planting geometry and three irrigations (20, 40 and 60 DAS) is conducive to produce maximum seed yield (kg•ha −1 ) of sesame

Effect of Sowing Dates on Growth, Yield and Grain Quality of Hybrid Maize

This study was conducted during 2013-14 at Student Farm, | department of Agronomy, Faculty of Crop Production, Sindh Agriculture University, Tandojam. The experiment was laid out in Randomized Complete Block Design (factorial) with three replications having net plot size 3x4m=(12m2). The effect of three sowing dates 25thOctober, 10th November and 25th November on three hybrid maize varieties Pioneer 1543, Syngenta 4841 and Monsanto DK-6142 was studied. Yield components and grain quality parameters such as plant height, number of cobs per plant, cob length, grains per cob, grain yield, protein, starch and oil content of maize varieties were significantly affected by different sowing dates. It was concluded from the finding of present research work that all quantity and quality traits were promising when the sowing was completed up to 25th October. Further delay of the sowing had negative effects on the performance of quantity and quality of maize. Hybrid maize variety Pioneer 1543 was promising variety which gave the grain yield more than 8312 kg ha-1

CROP ROTATIONAL EFFECTS ON INFESTATION OF STEM BORERS IN RICE

The present study investigates the impact of crop rotation on the infestation of stem borers in rice crops. This research was carried out in the field at Shaheed Zulfiqar Ali Bhutto Agricultural College Dokri, Sindh, Pakistan. Several rotation practices were tested, including Rice fallow Rice, Rice-Wheat-Rice, Rice-Gram-Rice, Rice-Barseem-Rice, and Rice-Mustard-Rice. The results of the study revealed interesting findings. The lowest infestation rate, approximately 1.92% of rice stem borers, was observed in the Rice-Barseem-Rice rotation. This was followed by Rice-Mustard-Rice at 2.18%, Rice-Gram-Rice at 2.40% and Rice-Wheat-Rice at 3.21%. In contrast, the highest infestation rate, reaching 4.99%, was recorded in the Rice-fallow-Rice rotation system. These findings suggest that incorporating winter rotation crops such as Mustard, Barseem, and Gram into the cropping system can significantly reduce the population density of rice stem borers. On the contrary, mono-cropping, as exemplified by the Rice-fallow-Rice rotation, appears to favor stem borer infestations. In light of these results, it is recommended that further research and understanding be developed to implement cultural control methods and ensure ecological safety within winter crop rotation systems. This study underscores the importance of diversified crop rotation practices in mitigating the infestation of harmful pests like rice stem borers, contributing to sustainable agriculture and higher crop yields
