This paper examines the effects of planting date (early planting, mid-season planting and late-season planting) and weeding regimes (two weeding before harvesting, three weeding before harvesting and weed free plots) on yield of Okra (Abelmoschus esculentus L. Moench) in the Tolon district of Northern Ghana. The results show that different weed species, categorized as broad leaves, grasses and sedges, were dominant depending on the planting date and weeding regime. While there was no significant interaction (p>0.05) between planting date and weeding regime on fruit yield, nor significant impact of planting date as a sole treatment on fruit yield, the results showed the existence of significant effect of weeding regime as a sole treatment on yield and yield parameters of okra (p<0.05). Triple weeding resulted in okra yields comparable to the weed-free treatments (mean of 6000 kg/ha to 6300 kg/ha, p>0.05) but significantly higher (p<0.05) and about triple the yield observed in the treatments with double weeding regimes (mean of 1800 kg/ha to 2300 kg/ha). As cost of production, besides the cost of weeding, remains same for all treatments, Triple weeding is recommended for the small-holder farmer. It is associated with less labor cost compared to continuous weeding in the weed free treatments, and the triple gains in yield could offset the additional labor cost incurred in the triple weeding compared to the double weeding regimes.

Coconut (Cocos nucifera L.) is by far the most extensively cultivated plantation crop in Sri Lanka. It is essentially a small holder crop comprising about 86% of small. holdings and homesteads and the balance belonging to the estate sector. The growth habit of the palm and its canopy structure requires a wide, spacing between palms, which permits abundant sunlight to the understory. As a result, the unutilised space beneath the plantation becomes invaded by a wide range of perennial and annual weed species. Such weeds invariably compete with coconut for soil moisture and nutrients, affecting its growth and yield and obstructing routine estate practices. Management of the understory weed growth is, therefore, considered an essential step in maintaining the plantation. In fact, the cost of weeding accounts for a substantial proportion of the total recurrent expenditure for maintenance.

A field study was carried out at the Kwara State University Teaching and Research Farm, Malete, to evaluate the response of vegetative growth and immature fruit yield of okra (Abelmoschus esculentus (L.) Moench) to three fertilizer types and three times of application. The fertilizer types, used at the rate of 60 kgN/ha, were Kwasu organic-based fertilizer type 2 (KOBF-2), Aleshinloye organo-mineral fertilizer grade A (AOMF-A), and inorganic NPK 15- 15-15 fertilizer (NPK), each applied at planting time, 2 weeks after planting (WAP), and 4 WAP. The trial was laid out in a 3 x 3 factorial arrangement in a randomized complete block design and replicated three times. All the data collected were subjected to analysis of variance, using the SAS statistical package, and the treatment means were separated using Duncan?s Multiple Range Test at 5% probability level. The result indicated no significant differences in plant height, number of leaves/plant, number of fruits/plant, and the average length of the fruits between fertilizer types and application times. However, there were significant differences in leaf area/plant at 6WAP and fruit yield. Irrespective of the times of application, KOBF-2 gave significantly higher immature fruit yield (2.84 t/ha) than NPK (1.93 t/ha) and AOMF-A (1.72 t/ha). The results thus suggest that the new organic-based fertilizer formulated in this study (KOBF) deserves incorporation into national fertilizer programs for sustainable crop production.

Herbicide Use

Experiments were conducted in 1987 and 1988 at two locations each year to determine how two weed management strategies and three planting dates affected the cost and amount of herbicide needed to control weeds in peanuts. Weed management strategies used for each planting date included preventive, which duplicated a standard grower program, or an integrated weed management system. The least expensive strategy depended upon weed species composition, weed populations and planting date. In all cases, the integrated weed management strategy required less herbicide (acid equivalent or active ingredient) than the preventive strategy.

Abstract Artificial pruning is one way in which an increase in end product quality can be achieved. Secondary data as well as a field study were used to evaluate the cost efficiency of pruning in immature oak stands in southeastern Missouri. A pruning time prediction model was developed from data collected during a field study of pruning. Number and size of limbs as well as height of log segment were found to be important factors affecting pruning time. The TWIGS growth and yield model was used to project tree growth from which the volume of clear wood produced as a result of pruning was estimated. When labor costs were included, all present net worths (PNWs) of the pruning investment were found to be negative due to the small amount of clear wood produced and a small price difference between clear and knotty wood. Excluding labor cost, assuming that it will be absorbed by the landowner, PNW was positive for 60, 70, and 80 yr rotations at only the 3.0% discount rate. The knot-free stumpage price necessary to earn a 5.0% discount rate was estimated and found to be substantially higher than present prices in the region. Because of low return and potential risk of epicormic branching, artificial pruning of immature oak stands is not an economical management option. South. J. Appl. For. 19(1):14-17.

A field experiment was carried out at College Orchard, Department of Vegetable Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during 2014 to 2017 to investigate integrated weed management on growth, yield and economics in okra (Abelmoschus esculentus (L.) Moench) cv. COBhH 1 during kharif seasons. The experiment was laid out in Randomized Block Design (RBD) with seven treatments and replicated three times. The growth and yield attributes viz., plant height, number of fruits per plant, fruit yield per plant, fruit length, fruit girth, fruit yield kg per plot and fruit yield (q/ha) differed significantly due to different treatments. Growth and yield attributes increased significantly in weed free check (T2 ) which led to appropriate timing of weeding which reduced the influence of weed interference and increased the yield in okra. The results revealed that weed free check (T2 ) recorded the higher plant height (151.80 cm), number of fruits/plant (27.30) with an average fruit yield of 0.501 g per plant, fruit length (13.53 cm), fruit girth (7.53 cm), fruit yield (233.9 q/ha) and low weed density (12.03/m2 ) at 60 days after sowing. Whereas, the high cost benefit ratio (2.88) was recorded in pre emergence of pendimethalin @ 1.0 kg/ha + one hand weeding (T4 ) which also recorded 23.36 number of fruits/plant with fruit yield of 223.0 q/ha. It is therefore recommended that pre emergence application of pendimethalin @ 1.0 kg/ha + one hand weeding will be optimal for okra production in kharif season.

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.
