In arid and semiarid regions of northern China, there is an increasing interest in using water-saving superabsorbent polymer (SAP) for field crop production. Experiments were conducted during 2009 and 2010 to study the growth and yield characteristics of summer corn (Zea mays L.) under different (control, 0; low, 10; medium, 20; high, 30 and very high, 40 kg/ha) rates of SAP in a drought-affected field of northern China. Corn yield increased slightly following SAP application at low and medium rate, but significantly at high and very high rates by 22.4 and 27.8%. At the same time, plant height, stem diameter, leaf area, biomass accumulation, harvest index and relative water content as well as protein, sugar and starch contents in the grain increased significantly following SAP treatments. The optimum application of superabsorbent polymer for corn cultivation in the study area would be 30 kg/ha as it best increased the grain yield and quality and maintained higher levels of soil nutrients. Lower rates (10 and<br />20 kg/ha) or higher (&ge; 40 kg/ha) rates would neither be sufficient nor economical. We suggest that the application of SAP at 30 kg/ha could be an efficient and economic soil management practice for summer corn production in the drought affected regions of northern China or other areas with similar ecologies.

With increased pressure on cropping land, traditional soil fertility regeneration has become less effective. Farmers with no alternatives would therefore be compelled to cultivate on marginal lands, highly risking crop failure and food security. Soil fertility can be improved by employing Agroforestry principles of incorporating organic inputs into the soil. This study investigated the effects of leaf mulch of Gliricidia sepium, Senna siamea and Leucaena leucocephala and their combination with inorganic fertilizer on maize (Zea mays L) growth and yield. The study was conducted in a randomized completely block design at the Faculty of Renewable Natural Resource farm, KNUSTGhana. Fresh leaf biomass at 5 t ha]1 weight was incorporated into the soil and compared with the addition of inorganic fertilizer at 0, 30 and 60 kg N ha Â]1 levels. Soil laboratory analysis showed that the mineral content of the leaf biomass varied with L. leucocephala having the highest N content and S. siamea having the lowest N content. The addition of the different levels of the inorganic fertilizer to the leaf biomass significantly influenced the yield of maize. Combining leaf biomass of S. siamea, G. sepium and L. leucocephala with inorganic fertilizer significantly increased maize yield and can be recommended for improving maize and other crop production.

The purpose of this research is to study interaction of humic substances extracted from subbituminus coal with P fertilizer on the chemical properties of Ultisol and crop production of corn (Zea mays L.). The experiment was designed in completely randomized design having 2 factors (4 x 4) with 3 replications. The first factor was dose of humic substances (A) which consists of 4 levels (A1 = 0 ppm, A2 = 400 ppm, A3 = 800 ppm, and A4 = 1200 ppm). The second factor was level of fertilizer P (B) (B1 = 100% recommendation, B2 = 75% recommendation, B3 = 50% recommendation, and B4 = 25%). The result showed that : 1) There is no interaction between humic substances and P fertilizer on the chemical nature of Ultisol and crop production of corn (Zea mays L.) 2) Use of humic substance for 800 ppm with some level of P fertilizer could improve some chemical properties of Ultisol such as decreased in content of Al-exch by 0,38 me/100 g soil, increased in P-available by 22,16 ppm, CEC by 8,42 me/100 g soil and P nutrient by 0,10 %, as well as corn yield by 25,67 g/pot compared to soil without humic substances 3) The use of SP-36 for 50 % with some level of humic substances increased in plant height by 26,58 cm, P nutrient by 0,11 %, and the use of 75 % SP-36 increased corn yield by 5,84 g/pot compared to 25% of P recommended.Keywords : humic subtances, subbituminus coal, P fertilizer.

An experiment was conducted during the Rabi season of 2020 at Fodder Production Farm of Livestock Research Station (Sri Venkateswara Veterinary University), Lam Farm, Guntur. A.P, to find out the effect of basal application of Nitrogen and Zinc on growth and yield of Baby corn (Zea mays L.). The experiment was laid out in Randomized Block Design with 9 treatments and each treatment replicated thrice. Treatments consisted of combination of three levels of Nitrogen (80,100 and 120kg/ha) and three levels of Zinc (10, 20 and 30 kg/ha). It was observed that application of 100 kg Nitrogen /ha + 30 kg Zinc/ha, was found the best treatment for obtaining growth and yield attributes such as Plant height (178.46 cm), Plant dry weight (105.58 g), No. of leaves per plant (12.00), Leaf area index (3.07), No. of cobs per plant (4.19), Length of cob (20.72 cm), Length of the corn (9.06 cm), Girth of the cob (7.34 cm), Corn girth (3.42), Cob yield (16026.53 kg/ha) and Corn yield (2597.47 kg/ha in Krishna zone of Andhra Pradesh, India.
