Effects of organic manures and NPK fertilizers on okra (Abelmoschus esculentus L. Moench) plants were evaluated in the net house of the Department of Soil, Water and Environment, University of Dhaka. The experiment was conducted in a randomized design replicated thrice with eighteen treatments involving eight organic manures along with NPK and without NPK fertilizers. Growth parameters viz. plant height, leaf number, leaf area and dry weight of root, stem, leaf and fruits were assessed. The highest height (132.5 cm), leaf number (21.5) and leaf area (412.09 cm2) were found in T9: Shebok 10 ton ha–1 treatment. The highest dry weight of a plant (40.6 g), number of fruits per plant (8) and dry weight of fruit per plant (3.71 g) were found in T11:N30P18K25 kg ha–1 plus ACI 5 ton ha–1 treatment. Maximum protein (25.37%) was achieved in T11, phosphorous (0.481 mg kg–1) in T14 and potassium (4.50 mg kg–1) in T13 treatment. Results varied significantly (p≤0.5). The overall best growth performance and protein content was observed in T9:Shebok 10 ton ha–1 and T11:N30P18K25 kg ha–1 plus ACI 5 ton ha–1 treatment, respectively. J. Biodivers. Conserv. Bioresour.

Okra or Lady’s finger, botanically known as Abelmoschus esculentus (L.) Moench, is a tropical and sub-tropical indigenous vegetable crop commonly grown for its fibrous, slimy, and nutritious fruits and consumed by all classes of population. It has also several medicinal and economic values. Despite its many uses and potential value, its importance is under estimated, under-utilized, and considered a minor crop and little attention was paid to its improvement. The study was conducted to evaluate the effects of different planting densities and mulching materials on the growth and yield of okra grown in slightly sloping area in the marginal uplands in Sta. Rita, Samar, Philippines. A split-plot experiment was set up with planting density as main plot and the different mulching materials as the sub-plot which were: unmulched or bare soil, rice straw, rice hull, hagonoy and plastic mulch. Planting density did not significantly affect the growth and yield of okra. Regardless ofthe mulching materials used, mulched plants were taller and yielded higher compared to unmulched plants. Moreover, the use of plastic mulch resulted to the highest total fruit yield. The results indicate the potential of mulching in increasing yield and thus profitability of okra production under marginal upland conditions.

Temephos 1% atau lebih dikenal dengan abate dulu efektif untuk penanganan larva nyamuk, khususnya larva Aedes aegypti yang merupakan vektor utama dari demam berdarah. Akan tetapi penggunaan yang terus menerus dan tidak terkontrol dapat menyebabkan terjadinya resistensi temephos. Tujuan dari penelitian ini adalah untuk mencari larvasida alami yang dapat digunakan sebagai alternatif atau pengganti temephos, salah satunya adalah buah okra. Penelitian ini merupakan penelitian eksperimental, dengan lima kali pengulangan dan konsentrasi masing-masing 1%,2%,4%,8%, dan 16%, kontrol negatif, dan temephos 1% sebagai kontrol positif, dan dilakukan pengamatan selama 24 jam untuk melihat jumlah kematian larva. Hasil percobaan serbuk buah okra dengan berbagai konsentrasi terhadap larva instar III Aedes aegypti menunjukkan hasil nilai LC50 sebesar 4,143% dan LC90 sebesar 12,778%. Serbuk buah okra dapat bertindak sebagai racun dan bersifat sebagai racun kontak bagi larva Aedes aegypti. Dapat disimpulkan bahwa dosis efektif serbuk buah okra untuk mematikan larva Aedes aegypti adalah 12,778 %. Kata kunci: Aedes aegypty, temephos 1%, larvasida, serbuk buah okra
