The field experiment was conducted, in the fields of Hamelmalo Agricultural College, to evaluate the response of sowing-dates and PK (Phosphorous and Potassium) fertilizer levels on phenological aspects, yield and yield components of okra (Abelmoschus esculentus L). The experiment was done through a factorial randomized complete block design (RCBD) where each treatment was replicated three times. The two factors were: sowing-dates which was composed of three sowing dates; namely, middle kiremti (end of July i.e., mid-summer), late kiremti (middle of August- late-summer) and early qewee (early September-early autumn) and P: K fertilizers which was composed of five rates (0kg/ha, 125 kg/ha (75:50), 150 kg/ha (90:60), 175 kg/ha (105:70) and 200 kg/ha (120:80). Results showed that, the highest significant mean values of leaf area (389.4cm2), leaf numbers (28.2) were recorded from middle kiremti sowing date coupled with 320kg/ha and 175kg/ha PK rates respectively. Besides this the highest significant values of both number of fruits (43.8) and total yield (15.26t/ha) were obtained from highest PK rate coupled with late kiremti and middle kiremti respectively.  The sole effects of the PK rates as well as the sowing dates were found to be significant on all the parameters mentioned above including individual fruit weight.  It is therefore the sowing during late kiremti coupled with application of 200kg/ha kg/ha was the best for getting the best economic returns.

An experiment was carried out at the Olericulture field of Horticulture Research Centre of BARJ, Joydebpur, Gazipur during September 2006 to April 2007 to investigate yield and yield attributes of sweet pepper as influenced by plant spacing and sowing time. There were altogether 21 treatments comprising seven sowing dates viz. 1 September, 15 September, 1 October, 15 October, 30 October, 15 November, 30 November and three spacings viz. 50 × 50 cm, 50x40 cm, and 50 × 30 cm. The experiment was laid out in a Randomized Complete Block Design (factorial) with three replications. The results of the experiment showed that majority of the yield and yield components significantly varied with variation of spacing and sowing time. Only number of fruits per plant and fruit yield per plant resulted significantly higher which reflected higher yield for 1 October sowing. The number of branches per plant, number of fruits per plant, fruit length, individual fruit weight, yield per plant were found significantly increased with the increasing plant spacings but other parameters were found to be significantly increased with the decreasing plant spacing. The combined effect of sowing date and plant spacing also had significant effect on different growth and yield parameters and yield. The highest yield (19.36 t/ha) of fruit was recorded from the earlier sowing (1 October) with the closest spacing (50 × 30 cm). But reasonable yield could be obtained up to 30 October with same spacing. Keywords: Sowing time and plant spacing; yield and yield attributes; sweet pepper.

A field experiment was conducted at KVK Kalyan instructional farm at Jahajpur of Purulia district of West Bengal during rabi season of 2018-19 to assess the effect of Biochar and Vermicompost as organic soil amendments on yield of brinjal under red and lateritic soils of Purulia, West Bengal. Biochar and vermicompost applied alone additionally in the farmers practice. The experiment design adopted was Randomised Block Design (RBD) having four replications with three treatments The treatments comprises of T1: Application of N:P:K  70:30:30 kg/ha (Farmers’ practice) + FYM @ 2 t/ha, T2: Farmers practice  + Vermicompost @ 5 t/ha, T3: Farmers practice  + Biochar @ 10 t/ha. The growth and yield attributing characters recorded was plant height at 30, 60, 90 and 120 DAT, number of fruits per plant, average fruit weight, yield per plant and total yield. Application of biochar and vermicompost had a significant effect on the growth and yield of Brinjal. Highest growth yield attributes and highest fruit yield (22.36 t/ha) were obtained due to the application of farmers practice + vermicompost @ 5 t/ha (T2). Application of biochar along with farmers’ practice did not show any significant results in brinjal yield as compare to vermicompost application treatment. The potential for long-term benefits of biochar remain to be explored through continued research in the red laterite soils of Purulia district of West Bengal.

Downy Mildew Disease

Downy mildew caused by Sclerospora graminicola (Sacc.) Schroet is a major limiting factor to the production of pearl millet globally. Therefore, a field trial was carried out during the 2018 and 2019 rainy seasons at Bauchi and Maiduguri located in the Northern Guinea and Sudan Savannah of Nigeria, respectively. The aim was to evaluate the effects of different sowing dates and a fungicide on seedlings establishment of three pearl millet genotypes infected with downy mildew disease. Randomized Complete Block Design was used with a factorial arrangement of treatments, which comprised three pearl millet genotypes (Gero, Maiwa, Dauro), three sowing dates (late-June, mid-July and late-July) and metalaxyl fungicide (treated and untreated). Results for genotypes consistently showed that Maiwa performed better than Gero and Dauro. In terms of the sowing date, the performance of millet was better in the first sowing date (late-June), followed by the second date (mid-July) and then the third date (late-July). Mean values of the seedling establishment were significantly decreased with delay in sowing date. Results, in respect of the fungicide treatments, generally indicated a higher seedling stands in the treated (78.6 - 87.4%) than untreated seed (70.9 - 81.1%) across the locations. These findings revealed that treated seeds with metalaxyl fungicide and early sowing give better seedling establishment in pearl millet.

Pepino melon (Solanum muricatum Ait.) is an exotic vegetable whose consumption is on the increase in Kenya due to its health and nutritional benefits. A study was conducted at Egerton University, Kenya in 2018-2019 to investigate the effect of NPK fertilizer rates (0, 100, 200. 300 and 400 kg ha-1) on growth and yield of field and greenhouse grown pepino melons. The experiment was laid in a randomized complete block design with three replications. Data was recorded on plant height, stem diameter, number of leaves per bush, number of branches, days to 50% flowering, fruit weight and total yield. Data were analyzed using analysis of variance with the SAS statistical package. Significant means were separated using Tukey’s Honestly Significant Difference at p ≤ 0.05. Results indicated that NPK fertilizer rates and growing environment influenced growth and yield of pepino melon. At 100 DAP plants grown in the greenhouse and supplied with 200 kg NPK ha-1 had a stem diameter of 14.01 mm which was significantly bigger p ≤ 0.05 compared to those grown in the field and supplied with 300 kg NPK ha-1 with a stem diameter of 11.71 mm in trial two. Application of 300 kg NPK ha-1 for field grown pepino melons gave the highest yield of 1102.48 kg ha-1 and 1060.55 kg ha-1 in trial one and two respectively. In conclusion, application of 300 kg ha-1 of NPK fertilizer for field grown pepino melon is recommended.

ABSTRACT Brazilian off-season cropping is increasing the production of cereals, particularly in the Brazilian savannah. Sorghum has been widely used for its grain production capacity and dry matter. Several hybrids are commercially available, each with its own peculiar nutrient absorption capacity. Thus, this study analyzed the agronomic characteristics and nutrient exportation in grain sorghum hybrids sown on different dates. The experiment was conducted at the Paulista Agency Regional Center of Agricultural Technology (APTA) in the city of Votuporanga, São Paulo. The experiment was conducted in a randomized block design with four replications and 4 hybrids. Sorghum hybrids (50A10, 50A50, BUSTER and 1G282) were the different treatments sown on four different dates, beginning with February 26, 2013, with the other dates 17, 30 and 41 days after the first sowing (DAFS). Each sowing date was considered an individual experiment and, subsequently, grouped for analysis to compare characteristics. Macronutrient content in the grain, one thousand grain weight, productivity and exportation of macronutrients (kg ha-1) by grains in the area were evaluated. The productivity of the sorghum hybrids varied depending on the sowing dates. The one thousand grain mass of the sorghum hybrids varied depending on the sowing dates. The average exportation of macronutrients by sorghum grains is as follows, in decreasing order: N> K> P>Ca> Mg> S. The mean values of macronutrient accumulation needed to produce one ton of sorghum grains are as follows: 20.05 kg N, 3.33 kg P, 3.70 kg K, 3.49 kg Ca, 1.77 kg Mg, and 0.72 kg S.

Information on some agronomic practices are required for muskmelon production as there is no record of its production in Ado-Ekiti. A field study of 3 x 2 factorial experiment of sowing dates (January, May and September) and NPK 15:15:15 fertilizer application (0 and 333 kg ha-1) was laid out in a Randomized Complete Block Design in three replicates at the Teaching and Research Farm of Ekiti State University, Ado-Ekiti, Nigeria. Data collected on the number of leaves and branches, leaf area, vine length, day to flowering, 50% flowering, number of fruit, fruit size and yield were subjected to analysis of variance and treatment means separated by Duncan's Multiple Range Test at 5% probability. Dates of sowing did not significantly influence growth but muskmelon planted in May gave a higher number of leaves plant-1, leaf area and vine length. Fertilized plants produced better growth and earlier flowering than unfertilized plants. The number of fruits ha-1, average fruit weight and fruit yield ha-1 of 11606, 0.78 kg and 9.09 t ha-1 respectively were produced by fertilized plants which were significantly higher than 10036.70, 0.28 kg and 2.44 t ha-1 from unfertilized plants. Muskmelon planted in September produced a higher number of fruits and fruit yield of 12418 and 11.29 t ha-1 while muskmelon planted in May produced higher fruit weight (0.94 kg) but these did not differ significantly from other sowing dates. Planting muskmelon under the rain-fed condition with adequate fertilizer application gave better performance and is thereby recommended for muskmelon production in Ado-Ekiti.
