Abstract Cantaloupes, Cucumis melo, ‘Topmark’ were direct seeded on 3 Mar into single row “yuma beds” on 203 cm centers and thinned to 30 cm intervals at the University of Arizona, Yuma Valley Agricultural Center. Plots consisted of 4 beds, 18 m long with a 3.6 m buffer between plots. Plot preparation and seasonal maintenance followed local practices. Plots were arranged in a randomized complete block design with 4 replicates. Applications were made with a 4-row highpressure, electrostatic boom sprayer equipped with stainless steel, hollow-cone nozzles (TX-18) spaced at 50 cm and delivered 563 liters/ha at 400 psi. Admire was applied as a soil drench in 40 oz of water/plant one week after thinning (5 Apr). Foliar applications were initiated when immature whitefly densities exceeded 3 nymphs/leaf. A total of 3 applications of CGA215944 and Fenoxycarb were made on 29 Apr and 5, 14 May. The remaining foliar treatments were applied 5 times on 29 Apr, 5, 14, 20, and 28 May. The pH of the application water was 7.1. A spreader/sticker was not used. Insect data were collected only from the inner two beds of each plot. Plots were sampled weekly beginning on 14 Apr, and terminating on 9 June. Adult SPWF were assessed by randomly selecting 20 leaves from the terminal area on primary vines (4th fully expanded leaf from the apex of the vine) and counting the number of live adults on the bottom surface. Counts were made at sunrise between 0500-0600 hrs. Immatures were assessed by counting the number of eggs, small nymphs, large and red-eyed nymphs, and eclosed pupal cases on two-cm2 disk sections from each of 10 leaves per plot.

Abstract Cantaloupes were direct seeded on 9 Mar into pre-irrigated beds spaced 80 inches apart at the University of Arizona, Yuma Valley Agricultural Center, Yuma, AZ. Plots consisted of 4 beds, 60 ft long with a 13 ft buffer between plots. Plot preparation and seasonal maintenance followed local practices. Plots were established and insecticide incorporated with furrow irrigation. Plots were arranged in a RCB design with 4 replicates. Foliar applications were made with a tractor drawn sprayer that delivered 48 gpa at 320 psi on 13 Apr, 3, 17 May. Adult efficacy was assessed by counting the number of adults per leaf from each of 10 leaves per plot, 1 day before treatments were applied and 4, and 7 days after treatment. Because of heterogeneity of mean variances, insect data was first transformed (log10 x + 1) before analysis of variance. Treatment differences among means were estimated with the Ryan-Einot-Gabriel-Welsch multiple F test.

We investigated the interaction between genotype by trait, and an experiment was conducted at the University of Debrecen. Two maize cultivars, FAO340 and FAO410, were studied in a randomized complete block design with four replications. This experiment was applied to the six fertilization treatments. Fertilizer levels were NPK0 (control) (N:0, P2O5:0, K2O:0), NPK1 (N:30, P2O5:23, K2O:27), NPK2 (N:60, P2O5:46, K2O:54), NPK3 (N:90, P2O5:69, K2O:81), NPK4 (N:120, P2O5:92, K2O:108), and NPK5 (N:150, P2O5:115, K2O:135). The first principal component showed 54.24%, and the second principal component showed 20.75%, which explained the total squares interaction using the AMMI model in the case of the FAO410 hybrid. As regards the FAO340 hybrid, the first principal component showed 58.18%, and the second principal component showed 18.04%, explaining the total squares interaction using the AMMI model in the FAO410 hybrid. In the GGE biplot on FAO410, the first and the second principal components covered 91.20% of the total data in this analysis. Accordingly, the desirable treatment was NPK5, followed by NPK4, NPK2, NPK3, NPK1, and NPK0. NPK4 and NPK5 had the most desirable treatments for the number of seeds per row, chlorophyll, weight of 1000 seeds, and stem diameter in the case of the FAO410 hybrid.

Ornamental bulbous crops emergence and yield can be improved by its emergence from soil. The response of Caladium to different planting depths and dates was investigated at Ornamental Horticulture Nursery, Department of Horticulture, The University of Agriculture, Peshawar during the year 2008. Randomized Complete Block Design in a split plot arrangement was used repeated three times. Sowing dates (30th March, 15th April and 30th April) were allotted to main plots whereas planting depths (2.5 cm, 5 cm, 7.5 cm and 10 cm) were kept in sub plots. Findings revealed that Caladium tubers sown on 30th March took maximum days to sprouting (33), produced maximum number of sprouts plant-1 (2.21), gained maximum tuber size (40.88 cm3) with high tuber yield (5397 kg ha-1). On the other hand, tubers sown on 30th April took less days to sprouting (20.21), produced less number of sprouts plant-1(1.53), produced small tuber (33.28 cm3) and total tuber yields was also less (4374 kg ha-1). In case of planting depth, Caladium tubers sown at a depth of 7.5cm resulted in maximum plant height (52 cm), tuber size (41.76 cm3), and tuber yield (5288 kg ha-1) while maximum number of tubers plant-1 (1.92) was observed at a depth of 10 cm. Tubers sown in 2.5 cm depth resulted in minimum tuber yield (4538 kg ha-1) and plant height (46.56 cm). To maximize vegetative as well as tubers production of Caladium cv. Florida sweet heart, it shall be sown on 30th March with 7.5cm depth.

An experiment was conducted at the Bangladesh Jute Research Institute (BJRI), Regional Station, Kishoreganj during July to December of 2010 and 2011 to investigate the effect of spacing and de-topping on yield and quality of kenaf seeds cv. HC-95 grown under direct seeding method. Three plants spacings (40 cm × 15 cm, 30 cm × 15 cm and 20 cm × 15 cm) and four de-topping treatments (no de-topping, de-topping at 15, 30 and 45  days after emergence (DAE) were applied in a Randomized Complete Block Design (RCBD) with three replications. The highest yield of kenaf seed (1403 and 1646 kgha-1 in 2010 and 2011, respectively) was obtained from sowing at 30 cm × 15 cm spacing. The best quality seed in respect to germination and vigour was also obtained from sowing at 30 cm × 15 cm spacing. The highest seed yield, germination and vigour of seed were obtained for de-topped at 45 days after emergence. It is concluded that the highest seed yield and quality of late season direct seeded kenaf could be obtained by sowing at a spacing of 30 cm x 15 cm and de-topping at 45 days after emergence.

[PRODUCTIVITY AND FRUIT QUALITY OF CANTALOUPE AT DIFFERENT RATES OF FRUIT THINNING AND NPK FERTILIZER APPLICATION]. Productivity and fruit quality of cantaloupe depend on the availability of nutrients and the number of fruits maintained. The aim of this study was to compare the productivity and fruit quality of cantaloupe at different rates of fruit thinning and NPK fertilizer application. The research was conducted in August-October 2020 on street Kapuas V, Lingkar Barat Village, Gading Cempaka District, Bengkulu city. A field experiment was arranged in a randomized complete block design (RCBD) with 3 replications for alloting two factorial treatments structure, namely rates of fruit thinning (no fruit thinning, thinned to one fruit /plant, thinned to two fruits/plant, and thinned to three fruits/plant) and rates of NPK fertilizer application (400, 600, and 800 kg/ha) on rhe experimental plots. The results showed that fruit thinnings resulted no increament in crop productivity, but the fruit quality was improved as fewer number of fruits were retained on each plant. The NPK fertilizer at 400, 600, and 800 kg/ha were not able to increase the productivity of cantaloupe  and the quality of the  produced fruit when  the application were made only at planting and 23 days after planting.

Jhum is a customary farming which is very important for the livelihood of the alpine people of Bangladesh. Total productivity of the traditional practice of jhum cultivation is very low. The study was conducted to identify the yield gap between improved and local practices in Bandarban district of Bangladesh during March to September; 2017.The experiment was laid out in randomized complete block design (RCBD) with ten replications. Improved jhum practice produced the higher yields of rice (3113kg/ha), seed cotton (456 kg/ha), sesame (478 kg/ha) and maize (627 kg/ha) than traditional local jhum. Rice Equivalent Yield (REY) was also higher (40.23%) in improved jhum (6786.8kg/ha) than local jhum (4339.8 kg/ha). Improved jhum’s rate of returns (2.15) was higher than traditional jhum’s rate of returns (1.56). Improved practice in jhum cultivation increased yield and it was economically profitable over traditional practice.J. Bangladesh Agril. Univ. 16(2): 193-197, August 2018
