Yield and Quality Aspects of ‘Sra Roucha’ Seedless Grapes as Affected by Gibberellic Acid

‘Sra Roucha’ is an early ripening seedless variety grown successfully under Steppe climate of Afghanistan. Its main problems are lower yield and quality, in terms of, cluster compactness, berry size and firmness. This experiment was undertaken for three growing seasons (2015-2017) at Ordokhan research station in Herat province of Afghanistan to investigate the effect of GA3 on yield, cluster and berry characters as well as sensory features. Treatments were: control, 10mg/L GA3 pre-bloom; 20mg/L GA3 pre-bloom; 10mg/L GA3 at 40% bloom; 20mg/L GA3 at 40% bloom; 10mg/L GA3 at 40% bloom + 10mg/L GA3 at 80% bloom; 20mg/L GA3 at 40% bloom + 20mg/L GA3 at 80% bloom; 10mg/L GA3 pre-bloom + 60 mg/L GA3 at 4 mm berry-size stage; 10mg/L GA3 pre-bloom + 60mg/L GA3 at 4 mm berry-size stage). Each treatment was replicated thrice with one vine per replicate. The experiment was run as split-plot in the frame of randomized complete block design. Data pertinent with sensory attributes were analyzed by Friedman’s non-parametric two-way ANOVA. Results showed that GA3 treatments significantly affected yield, cluster length, weight and compactness, berry diameter, berry length and berry TSS, color, taste and firmness. Application of 20 mg/L GA3 before flowering plus 60 mg/L GA3 at 4 mm berry-size stage, resulted in higher yield, cluster and berry characteristics as well as berry sensory features. Therefore, GA3 (20 mg/L pre-bloom + 60 mg/L at 4mm berry-size stage) is the reasonable technique for enhancing yield and quality aspects of ‘Sra Roucha’ seedless grapes.

Response of Zea Mays L to Tillage and Urea Fertilizer

The purpose of cultivation intensity and using kind Urea mature as an activity in corn culture creates the best environmental to plant growth and yield. The experiment was conducted in Sempaja village-Samarinda district. Randomized Split-Plot Design analysis in Randomized Block Design was used with 2 treatments and 3 replications. The treatments consist of two method of tillage (no tillage and conventional tillage) and two kind of urea mature (without Urea, Prill Urea and Briket Urea). The result showed that combination with conventional tillage method and briket urea give significantly effect on plant growth, yield components, and yield of corn.

Use of Intermediate Crops in the Establishment of Sown Parsley (Coriandrum Sativum L.) Plantations

The article states that the Coriandrum sativum L. plant can be used as an intermediate crop in the establishment of plantations. Experiments have shown that the use of intermediate crops in the cultivation of cashmere (Coriandrum sativum L.) on plantations has yielded effective results. In particular, in the cultivation of Coriandrum sativum L., the use of intermediate crops for one year increased the yield to 6%, and in the case of continuous crop rotation using intermediate crops, this figure increased to 12-14%. The use of intermediate crops in the cultivation of medicinal and spice plants is important not only to improve the structure of the soil, but also to increase its economic efficiency.

Integrated Use of Co-Compost with Lignite Fly Ash on Yield and Nutrient Uptake of Certain Crops

A field experiment was conducted to know the response of crops to combined application of co compost and lignite fly ash. Field experiments were conducted in experimental farm (rice and maize) and farmers holding (groundnut and brinjal) to study the response of certain crops to the application of co composts and lignite fly ash grown in clay loam and sandy clay loam soil, respectively. The treatment consisted of Dairy Farm Waste + Crop Residues, Pressmud+ Crop Residues, Dairy Farm Waste + Crop Residues + LFA @5 t ha-1, Dairy Farm Waste + Crop Residues + LFA @10 t ha-1, Dairy Farm Waste + Crop Residues + LFA @15 t ha-1, Pressmud + crop residues + LFA @5 t ha-1, Pressmud + crop residues + LFA @10 t ha-1and Pressmud + crop residues + LFA @15 t ha-1 .The grain and straw yield in rice and maize, pod and haulm yield in groundnut and fruit yield of brinjal were recorded during harvest. Differences in yield of crops between the treatments indicate significantly different effects on soil fertility and crop yield after long-term fertilization. The uptake of nutrients increased linearly with levels of LFA tried and it was higher when it was applied with co compost of pressmud and crop residue. The addition of co composts alone or with graded dose of lignite fly ash significantly improved the physical properties of the soil.
